Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,3-Difluorobenzyl)-1-ethyl-3-methyl-1H-pyrazol-5-amine hydrochloride.
N-(2,3-Difluorobenzyl)-1-ethyl-3-methyl-1H-pyrazol-5-amine hydrochloride (CAS 1855945-52-6) is a high-purity analytical reference standard with the molecular formula C13H15F2N3HCl and a molecular weight of 287.74 g/mol.
The molecular framework of N-(2,3-Difluorobenzyl)-1-ethyl-3-methyl-1H-pyrazol-5-amine hydrochloride (C13H15F2N3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 N-(2,3-Difluorobenzyl)-1-ethyl-3-methyl-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.
