Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-Chloro-5-methyl-2-(3-methylpiperazin-1-yl)pyrimidine hydrochloride (CAS 1261235-59-9), a certified reference material (molecular formula C10H15ClN4HCl, MW 263.17 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H15ClN4HCl, 4-Chloro-5-methyl-2-(3-methylpiperazin-1-yl)pyrimidine hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 4-Chloro-5-methyl-2-(3-methylpiperazin-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.
