Description
CATO supplies 4-chloro-3-methyl-1-phenyl-1H-pyrazol-5-amine hydrochloride (CAS 1909305-34-5), a certified reference material (molecular formula C10H10ClN3HCl, MW 244.12 g/mol) for analytical method development and quality control.
Structurally, 4-chloro-3-methyl-1-phenyl-1H-pyrazol-5-amine hydrochloride (C10H10ClN3HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 244.12 g/mol, it falls into the medium-molecular-weight range. 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.
CATO manufactures 4-chloro-3-methyl-1-phenyl-1H-pyrazol-5-amine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
