Description
CATO supplies (E)-4-(4-chlorostyryl)-2-((2,6-dichlorobenzyl)thio)pyrimidine (CAS 339278-35-2), a certified reference material (molecular formula C19H13Cl3N2S, MW 407.74 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, (E)-4-(4-chlorostyryl)-2-((2,6-dichlorobenzyl)thio)pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 407.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (E)-4-(4-chlorostyryl)-2-((2,6-dichlorobenzyl)thio)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.
