Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 241.26 g/mol gives 2-(7-Acetyl-5-oxo-2,3,5,6-tetrahydropyrrolo[2,1-b]thiazol-6-yl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(7-Acetyl-5-oxo-2,3,5,6-tetrahydropyrrolo[2,1-b]thiazol-6-yl)acetic acid (CAS 118792-70-4), molecular formula C10H11NO4S and molecular weight 241.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(7-Acetyl-5-oxo-2,3,5,6-tetrahydropyrrolo[2,1-b]thiazol-6-yl)acetic acid (C10H11NO4S) 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 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 2-(7-Acetyl-5-oxo-2,3,5,6-tetrahydropyrrolo[2,1-b]thiazol-6-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.
