Description
As a certified reference material (CRM), 2-[3-(4-chlorophenyl)-1-phenyl-1H-pyrazol-4-yl]ethan-1-amine 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.
2-[3-(4-chlorophenyl)-1-phenyl-1H-pyrazol-4-yl]ethan-1-amine hydrochloride (CAS 1235441-46-9), molecular formula C17H16ClN3HCl and molecular weight 334.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-[3-(4-chlorophenyl)-1-phenyl-1H-pyrazol-4-yl]ethan-1-amine hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.24 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.
