Chemical Structure
Description
The occurrence of 2,5-Dihydro-1H-pyrazol-3-amine hydrochloride is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,5-Dihydro-1H-pyrazol-3-amine hydrochloride (CAS 60777-00-6), a certified reference material (molecular formula C3H7N3HCl, MW 121.57 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-Dihydro-1H-pyrazol-3-amine hydrochloride (C3H7N3HCl) is characterized by 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2,5-Dihydro-1H-pyrazol-3-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.
