Flusilazole

Flusilazole is an organosilicon compound that is dimethylsilane in which the hydrogens attached to the silicon are replaced by p-fluorophenyl groups and a hydrogen attached to one of the methyl groups is replaced by a 1H-1,2,4-triazol-1-yl group. It is a broad-sepctrum fungicide used to protect a variety of crops. It has a role as a xenobiotic, an EC 1.14.13.70 (sterol 14alpha-demethylase) inhibitor, an environmental contaminant and an antifungal agrochemical. It is an organosilicon compound, a member of triazoles, a member of monofluorobenzenes, a conazole fungicide and a triazole fungicide. — ChEBI

How CAS 85509-19-9 is used on this site

CAS 85509-19-9 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 85509-19-9 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 85509-19-9 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.

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.
