Chemical Structure

2-Bromo-4-(trifluoromethyl)thiazole-5-carboxylic Acid CAS 162651-07-2 chemical structure

Description

The occurrence of 2-Bromo-4-(trifluoromethyl)thiazole-5-carboxylic Acid is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Bromo-4-(trifluoromethyl)thiazole-5-carboxylic Acid (CAS 162651-07-2), molecular formula C5HBrF3NO2S and molecular weight 276.03 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Bromo-4-(trifluoromethyl)thiazole-5-carboxylic Acid (C5HBrF3NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 276.03 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
