Imazamox

2-(4-isopropyl-4-methyl-5-oxo-4,5-dihydro-1H-imidazol-2-yl)-5-(methoxymethyl)nicotinic acid is a pyridinemonocarboxylic acid that is nicotinic acid which is substituted substituted at position 5 by a methoxymethyl group and at position 2 by a 4,5-dihydro-1H-imidazol-2-yl group, that in turn is substituted by isopropyl, methyl, and oxo groups at positions 4, 4, and 5, respectively. It is an imidazolone, an ether, a pyridinemonocarboxylic acid and a member of imidazolines. — ChEBI

  • Toxicity Summary: IDENTIFICATION AND USE: Imazamox is off-white powdered solid. It is a herbicide applied post-emergence in soybean. HUMAN STUDIES: In an in vitro study, human embryonic stem cells were treated with imazamox at a concentration of 0, 1, 10 or 100 umol/L, incubation did not induce cytotoxicity. ANIMAL STUDIES: In the acute toxicity studies, the substance has low acute toxicity when administered orally, dermally or by inhalation to rats. It is not a significant skin or eye irritant or a skin sensitizer. Imazamox showed no short-term and long-term toxicity after oral exposure to rats, mice and dogs up to the limit top dose level tested in each study. Based on available genotoxicity studies imazamox is unlikely to be genotoxic. The substance showed no carcinogenic potential in both species. In the multigeneration toxicity study, fertility and overall reproductive performance was not impaired. In developmental toxicity studies maternal toxicity in rats and in rabbits was observed. No developmental toxicity was observed in rats whereas agenesis of the intermediate lobe of lung and cervical hemivertebra was observed in rabbits. ECOTOXICITY STUDIES: Imazamox is practically nontoxic to avian s Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: Imazamox concentrations in whole and edible bluegill fish tissue were below the quantification limit, and the BCF for inedible tissue was less than 1X the concentration tested(1). An estimated BCF of 3.2 was calculated in fish for imazamox(SRC), using a log Kow of 0.73(2) and a regression-derived equation(3). According to a classification scheme(4), this BCF data suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), Koc values ranging from 5 to 143(2) indicate that imazamox is expected to have very high mobility in soil(SRC). The pKa values of imazamox have been reported as 2.3, 3.3 and 10.8(3), indicating that this compound will exist entirely in anion form in the environment and anions generally do not adsorb as strongly to soils containing organic carbon and clay as their neutral counterparts(4). Volatilization of imazamox is not expected to be an important fate process(SRC) because this chemical expected to exist as an anion in the environment and anions do not volatilize. Imazamox is primarily degraded by microbes in soil under aerobic conditions(2,3); essentially no degradation occurs under anaerobic conditions(2). Imazamox is considered moderately persistent with half-lives ranging between 15 to 142 days(2,3); its limited persistence will restrict leaching of imazamox into groundwater(2).

  • Environmental Fate: TERRESTRIAL FATE: In a field study with 5 soils, terrestrial dissipation half-lives ranged between 15 and 130 days(1). Leaching was found to be very limited in field studies(2). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), Koc values ranging from 5 to 143(2) indicate that imazamox is not expected to adsorb to suspended solids and sediment(SRC). The pKa values of imazamox have been reported as 2.3, 3.3 and 10.8(3) indicating imazamox will exist entirely in the anion form at pH values of 5 to 9 and, therefore, volatilization from water surfaces is not expected to be an important fate process(SRC). According to a classification scheme(4), an estimated BCF of 3.2(SRC), from its log Kow of 0.73(5) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Photodegradation can be rapid with a half-life of 6.8 hours observed in laboratory studies(2,3); this rate is only applicable at the surface of the water with rates decreasing with water depth. Imazamox is stable to hydrolysis at pH 5, 7 and 9(2). Imazamox is considered moderately persistent in soil with half-lives ranging between 15 to 142 days(2,3). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), imazamox, which has an estimated vapor pressure of 1.26X10-11 mm Hg at 25 °C determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase imazamox may be removed from the air by wet and dry deposition(SRC). Imazamox photolytically decays with reported half-lives of 6.8 hours (or 0.3 days)(5,6) and 78 minutes (or 3 days)(7) for primary degradation in aqueous media. Direct aqueous photolysis results in several stable degradates(7). Photolysis in soil is a slower process with a half-life of 65 days(6). The rate of photodegradation decreases in the presence of Cu(II) and Ca(II) salts which form stable complexes with imazamox(7). Source: Hazardous Substances Data Bank (HSDB)

How CAS 114311-32-9 is used on this site

CAS 114311-32-9 is the Chemical Abstracts Service identifier used to pin this page to a specific substance. In the current dataset, 1 EU annex record shares this identifier, which helps you cross-check whether the same substance appears under one regulatory context or several.

Use this page when a supplier specification, SDS or raw-material dossier gives you CAS 114311-32-9 and you need to see every linked Annex II–VI record in one place. The entry cards above are the quickest route to concentration limits, warnings, annex placement and product-type conditions.

Frequently asked questions

A substance identified by CAS 114311-32-9 may appear in multiple EU cosmetic regulation annexes when it is subject to different conditions in different contexts. For example, a substance might be restricted under Annex III with specific conditions, and the same CAS might also appear in Annex IV as an approved colorant under separate entry conditions. Each entry must be reviewed individually.

Cross-reference the CAS number against your raw material specification sheets and CoA documents. When a CAS appears in Annex II, verify absence. When it appears in Annex III, verify that concentration limits and product type conditions are met in your formulation. All annex entries sharing this CAS number are listed above.

A CAS number is assigned by the Chemical Abstracts Service (USA) and is globally recognised. An EC number is a European Commission identifier from inventories such as EINECS, ELINCS or the NLP list. Both identifiers may appear in EU cosmetic annex entries. Some substances have both, some have only one, and some older entries may have neither.
