Description
As a certified reference material (CRM), 4-Chloro-6-(piperazin-1-yl)pyrimidine hydrochloride 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 4-Chloro-6-(piperazin-1-yl)pyrimidine hydrochloride (CAS 203519-89-5), a certified reference material (molecular formula C8H11ClN4HCl, MW 235.11 g/mol) for analytical method development and quality control.
4-Chloro-6-(piperazin-1-yl)pyrimidine hydrochloride (C8H11ClN4HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
