Chemical Structure

Ethyl (Z)-2-((2,6-difluorobenzoyl)imino)-3,4-dimethyl-2,3-dihydrothiazole-5-carboxylate CAS 476643-66-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl (Z)-2-((2,6-difluorobenzoyl)imino)-3,4-dimethyl-2,3-dihydrothiazole-5-carboxylate.

Ethyl (Z)-2-((2,6-difluorobenzoyl)imino)-3,4-dimethyl-2,3-dihydrothiazole-5-carboxylate (CAS 476643-66-0), molecular formula C15H14F2N2O3S and molecular weight 340.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl (Z)-2-((2,6-difluorobenzoyl)imino)-3,4-dimethyl-2,3-dihydrothiazole-5-carboxylate (C15H14F2N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
