Ethyl 2-(2-tolyl)-4-phenylthiazole-5-carboxylate CAS 1965304-72-6

Description

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.

Ethyl 2-(2-tolyl)-4-phenylthiazole-5-carboxylate (CAS 1965304-72-6), molecular formula C19H17NO2S and molecular weight 323.41 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 2-(2-tolyl)-4-phenylthiazole-5-carboxylate (C19H17NO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).

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.
