7-Chloro-2-(difluoromethyl)thiazolo[5,4-d]pyrimidine CAS 1624606-96-7

Description

The occurrence of 7-Chloro-2-(difluoromethyl)thiazolo[5,4-d]pyrimidine is closely related to a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Chloro-2-(difluoromethyl)thiazolo[5,4-d]pyrimidine (CAS 1624606-96-7), molecular formula C6H2ClF2N3S and molecular weight 221.61 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system, 7-Chloro-2-(difluoromethyl)thiazolo[5,4-d]pyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 221.61 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
