Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1-Cyclopropyl-1H-pyrazol-3-yl)methanamine hydrochloride.
(1-Cyclopropyl-1H-pyrazol-3-yl)methanamine hydrochloride (CAS 2391987-09-8) is a high-purity analytical reference standard with the molecular formula C7H11N3HCl and a molecular weight of 173.64 g/mol.
The molecular framework of (1-Cyclopropyl-1H-pyrazol-3-yl)methanamine hydrochloride (C7H11N3HCl) is characterized by a nitrile group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 (1-Cyclopropyl-1H-pyrazol-3-yl)methanamine 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.
