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 (S)-5-Chloro-6-methyl-2-(piperidin-2-yl)pyrazolo[1,5-a]pyrimidine dihydrochloride (CAS 1956436-13-7), a certified reference material (molecular formula C12H15ClN4HCl, MW 287.19 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, (S)-5-Chloro-6-methyl-2-(piperidin-2-yl)pyrazolo[1,5-a]pyrimidine dihydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.19 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.
As a certified reference material (CRM), (S)-5-Chloro-6-methyl-2-(piperidin-2-yl)pyrazolo[1,5-a]pyrimidine dihydrochloride 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.
