Chemical Structure

pyrimidine-5-carbonyl chloride CAS 40929-48-4 chemical structure

Description

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 supplies pyrimidine-5-carbonyl chloride (CAS 40929-48-4), a certified reference material (molecular formula C5H9ClN2O, MW 148.59 g/mol) for analytical method development and quality control.

pyrimidine-5-carbonyl chloride (C5H9ClN2O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), pyrimidine-5-carbonyl 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.
