17969-26-5 6019AD C11H8ClNO2S [2-(3-Chloro-phenyl)-thiazol-4-yl]-acetic acid CAS 17969-26-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 17969-26-5 6019AD C11H8ClNO2S [2-(3-Chloro-phenyl)-thiazol-4-yl]-acetic acid.

17969-26-5 6019AD C11H8ClNO2S [2-(3-Chloro-phenyl)-thiazol-4-yl]-acetic acid (CAS 17969-26-5), molecular formula C11H8ClNO2S and molecular weight 253.70 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 17969-26-5 6019AD C11H8ClNO2S [2-(3-Chloro-phenyl)-thiazol-4-yl]-acetic acid (C11H8ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 253.70 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.

CATO manufactures 17969-26-5 6019AD C11H8ClNO2S [2-(3-Chloro-phenyl)-thiazol-4-yl]-acetic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
