Chemical Structure

(1-Methyl-1H-pyrazol-5-yl)methanamine dihydrochloride CAS 1185299-87-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(1-Methyl-1H-pyrazol-5-yl)methanamine dihydrochloride (CAS 1185299-87-9) is a high-purity analytical reference standard with the molecular formula C5H9N3HCl and a molecular weight of 147.61 g/mol.

The molecular framework of (1-Methyl-1H-pyrazol-5-yl)methanamine dihydrochloride (C5H9N3HCl) 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.

As a certified reference material (CRM), (1-Methyl-1H-pyrazol-5-yl)methanamine dihydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
