Chemical Structure

4-(Thiazol-2-yl)butanoic acid CAS 951217-56-4 chemical structure

Description

4-(Thiazol-2-yl)butanoic acid (CAS 951217-56-4), molecular formula C7H9NO2S and molecular weight 171.22 g/mol, is a CATO reference standard with documented purity and traceability.

4-(Thiazol-2-yl)butanoic acid (C7H9NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 4-(Thiazol-2-yl)butanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
