2-Chloro-N-(7-methyl-5-oxo-5H-thiazolo[3,2-a]pyrimidin-6-yl)nicotinamide CAS 941878-67-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 320.75 g/mol gives 2-Chloro-N-(7-methyl-5-oxo-5H-thiazolo[3,2-a]pyrimidin-6-yl)nicotinamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Chloro-N-(7-methyl-5-oxo-5H-thiazolo[3,2-a]pyrimidin-6-yl)nicotinamide (CAS 941878-67-7), a certified reference material (molecular formula C13H9ClN4O2S, MW 320.75 g/mol) for analytical method development and quality control.

The molecular framework of 2-Chloro-N-(7-methyl-5-oxo-5H-thiazolo[3,2-a]pyrimidin-6-yl)nicotinamide (C13H9ClN4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2-Chloro-N-(7-methyl-5-oxo-5H-thiazolo[3,2-a]pyrimidin-6-yl)nicotinamide 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.
