Chemical Structure
Description
As a certified reference material (CRM), 2-chloro-4-(dichloromethyl)pyrimidine 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.
CATO supplies 2-chloro-4-(dichloromethyl)pyrimidine (CAS 1803566-44-0), a certified reference material (molecular formula C5H3Cl3N2, MW 197.45 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 2-chloro-4-(dichloromethyl)pyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
