({5-[(dimethylamino)sulfonyl]-1,3-benzoxazol-2-yl}thio)acetic acid CAS 750624-70-5 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 ({5-[(dimethylamino)sulfonyl]-1,3-benzoxazol-2-yl}thio)acetic acid.

({5-[(dimethylamino)sulfonyl]-1,3-benzoxazol-2-yl}thio)acetic acid (CAS 750624-70-5), molecular formula C11H12N2O5S2 and molecular weight 316.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of ({5-[(dimethylamino)sulfonyl]-1,3-benzoxazol-2-yl}thio)acetic acid (C11H12N2O5S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), ({5-[(dimethylamino)sulfonyl]-1,3-benzoxazol-2-yl}thio)acetic 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.
