Chemical Structure

5-m-Tolyl-thiazole-4-carboxylic acid CAS 1017273-23-2 chemical structure

Description

The occurrence of 5-m-Tolyl-thiazole-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-m-Tolyl-thiazole-4-carboxylic acid (CAS 1017273-23-2), molecular formula C11H9NO2S and molecular weight 219.26 g/mol, is a CATO reference standard with documented purity and traceability.

5-m-Tolyl-thiazole-4-carboxylic acid (C11H9NO2S) contains a nitrogen-containing heterocyclic scaffold, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
