Chemical Structure

6-Oxo-1,6-dihydropyrimidine-5-sulfonyl chloride CAS 1211581-63-3 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 6-Oxo-1,6-dihydropyrimidine-5-sulfonyl chloride.

CATO supplies 6-Oxo-1,6-dihydropyrimidine-5-sulfonyl chloride (CAS 1211581-63-3), a certified reference material (molecular formula C4H3ClN2O3S, MW 194.60 g/mol) for analytical method development and quality control.

The molecular framework of 6-Oxo-1,6-dihydropyrimidine-5-sulfonyl chloride (C4H3ClN2O3S) is characterized by an amide group, a sulfone group, a carboxylic acid 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), 6-Oxo-1,6-dihydropyrimidine-5-sulfonyl chloride 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.
