4-Phenyl-2-(pyrazin-2-yl)thiazole-5-carboxylic acid CAS 1506428-22-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Phenyl-2-(pyrazin-2-yl)thiazole-5-carboxylic acid.

4-Phenyl-2-(pyrazin-2-yl)thiazole-5-carboxylic acid (CAS 1506428-22-3), molecular formula C14H9N3O2S and molecular weight 283.31 g/mol, is a CATO reference standard with documented purity and traceability.

4-Phenyl-2-(pyrazin-2-yl)thiazole-5-carboxylic acid (C14H9N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 4-Phenyl-2-(pyrazin-2-yl)thiazole-5-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
