Methyl 2-({5-[(methoxyimino)methyl]imidazo[2,1-b][1,3]thiazol-6-yl}sulfanyl)benzenecarboxylate CAS 338976-20-8 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 Methyl 2-({5-[(methoxyimino)methyl]imidazo[2,1-b][1,3]thiazol-6-yl}sulfanyl)benzenecarboxylate.

CATO supplies Methyl 2-({5-[(methoxyimino)methyl]imidazo[2,1-b][1,3]thiazol-6-yl}sulfanyl)benzenecarboxylate (CAS 338976-20-8), a certified reference material (molecular formula C15H13N3O3S2, MW 347.41 g/mol) for analytical method development and quality control.

The molecular framework of Methyl 2-({5-[(methoxyimino)methyl]imidazo[2,1-b][1,3]thiazol-6-yl}sulfanyl)benzenecarboxylate (C15H13N3O3S2) 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), Methyl 2-({5-[(methoxyimino)methyl]imidazo[2,1-b][1,3]thiazol-6-yl}sulfanyl)benzenecarboxylate 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.
