Chemical Structure

3-(4-Methoxyphenyl)-4-phenylthiazole-2(3H)-thione CAS 33682-67-6 chemical structure

Description

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.

3-(4-Methoxyphenyl)-4-phenylthiazole-2(3H)-thione (CAS 33682-67-6), molecular formula C16H13NOS2 and molecular weight 299.41 g/mol, is a CATO reference standard with documented purity and traceability.

3-(4-Methoxyphenyl)-4-phenylthiazole-2(3H)-thione (C16H13NOS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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