Chemical Structure

2-(2--Thiazolylazo)p-cresol CAS 1823-44-5 chemical structure

Description

2-(2--Thiazolylazo)p-cresol (CAS 1823-44-5), molecular formula C10H19N3OS and molecular weight 229.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-(2--Thiazolylazo)p-cresol is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.34 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.
