Diphenylamine

Diphenylamine is an aromatic amine containing two phenyl substituents. It has been used as a fungicide for the treatment of superficial scald in apples and pears, but is no longer approved for this purpose within the European Union. It has a role as a ferroptosis inhibitor, an antioxidant, a radical scavenger, a carotogenesis inhibitor, an EC 1.3.99.29 [phytoene desaturase (zeta-carotene-forming)] inhibitor and an antifungal agrochemical. It is an aromatic amine, a secondary amino compound and a bridged diphenyl fungicide. — ChEBI

  • Toxicity Summary: Diphenylamine uncouples mitochondrial oxidative phosphorylation, resulting in a decrease in hepatocellular ATP content and consequently hepatocyte injury (A15350). Short-term and long-term exposure in animal models results in altered haematological parameters, splenic erythropoiesis, splenic congestion and haemosiderosis (L2078).

  • Environmental Bioconcentration: BCFs ranging from 101 to 242 and 51 to 253 (species unidentified) were measured using 0.1 and 0.01 mg/liter of N,N-diphenylamine, respectively, and a 8-week study period(1). According to a classification scheme(2), these BCFs suggest the potential for bioconcentration in aquatic organisms is moderate(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1,900(SRC), determined from a log Kow of 3.50(2) and a regression-derived equation(3), indicates that N,N-diphenylamine is expected to have low mobility in soil(SRC). Volatilization of N,N-diphenylamine from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.7X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 6.7X10-4 mm Hg(4), and water solubility, 53 mg/liter(5). N,N-Diphenylamine is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). N,N-Diphenylamine is not expected to biodegrade in soil based on aqueous screening tests(6). N,N-Diphenylamine, present at 30 mg/l, reached 0% of its theoretical BOD in 2 weeks using an activated sludge innoculum at 100 mg/l and the Japanese MITI test(6).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1,900(SRC), determined from a log Kow of 3.50(2) and a regression-derived equation(3), indicates that N,N-diphenylamine is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 2.7X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 6.70X10-4 mm Hg(4), and water solubility, 53 mg/l(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 9.4 and 107 days, respectively(SRC). According to a classification scheme(6), BCFs ranging from 51 to 253(7), suggests bioconcentration in aquatic organisms is moderate(SRC). N,N-Diphenylamine was found to be not readily biodegradable in aqueous screening tests(7). N,N-Diphenylamine, present at 30 mg/l, reached 0% of its theoretical BOD in 2 weeks using an activated sludge innoculum at 100 mg/l and the Japanese MITI test(7). 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), N,N-diphenylamine, which has a vapor pressure of 6.7X10-4 mm Hg at 25 °C(2) is expected to exist solely as a vapor in the ambient atmosphere(SRC). Vapor-phase N,N-diphenylamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 1.9 hours(SRC), calculated from its rate constant of 2.0X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).

How CAS 122-39-4 is used on this site

CAS 122-39-4 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 122-39-4 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 122-39-4 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.

The INCI Checker accepts ingredient names, CAS numbers and EC numbers. Check this CAS number directly, then verify the result against supplier specification sheets and every linked annex condition.
