2,8-Dimethyl-4,5-dihydrobenzofuro[4,5-d]thiazole-7-carboxylic acid CAS 879916-91-3 chemical structure

Description

The occurrence of 2,8-Dimethyl-4,5-dihydrobenzofuro[4,5-d]thiazole-7-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.

2,8-Dimethyl-4,5-dihydrobenzofuro[4,5-d]thiazole-7-carboxylic acid (CAS 879916-91-3), molecular formula C12H11NO3S and molecular weight 249.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2,8-Dimethyl-4,5-dihydrobenzofuro[4,5-d]thiazole-7-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
