Description

Compared with other compounds in its class, the molecular weight of 194.21 g/mol gives 5-Aminobenzo[d]thiazole-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Aminobenzo[d]thiazole-2-carboxylic acid (CAS 353487-33-9), a certified reference material (molecular formula C8H6N2O2S, MW 194.21 g/mol) for analytical method development and quality control.

Structurally, 5-Aminobenzo[d]thiazole-2-carboxylic acid (C8H6N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 194.21 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
