Chemical Structure
Description
(5-Amino-1-methyl-1H-pyrazol-3-yl)methanol hydrochloride (CAS 1443279-32-0) is a high-purity analytical reference standard with the molecular formula C5H9N3OHCl and a molecular weight of 163.60 g/mol.
The molecular framework of (5-Amino-1-methyl-1H-pyrazol-3-yl)methanol hydrochloride (C5H9N3OHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 (5-Amino-1-methyl-1H-pyrazol-3-yl)methanol 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.
