3-Chloro-2-(trifluoromethyl)-4H-chromene-4-thione CAS 869986-01-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-2-(trifluoromethyl)-4H-chromene-4-thione.

3-Chloro-2-(trifluoromethyl)-4H-chromene-4-thione (CAS 869986-01-6), molecular formula C10H4ClF3OS and molecular weight 264.65 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 3-Chloro-2-(trifluoromethyl)-4H-chromene-4-thione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
