Description
As a certified reference material (CRM), 5-(Chloromethyl)-1-methylpyrazole 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 5-(Chloromethyl)-1-methylpyrazole Hydrochloride (CAS 1434128-56-9), a certified reference material (molecular formula C5H7ClN2HCl, MW 167.03 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 5-(Chloromethyl)-1-methylpyrazole Hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
