Chemical Structure

1-Methyl-N-(thiophen-2-ylmethyl)-1H-pyrazol-4-amine hydrochloride CAS 1856089-55-8 chemical structure

Description

1-Methyl-N-(thiophen-2-ylmethyl)-1H-pyrazol-4-amine hydrochloride (CAS 1856089-55-8), molecular formula C9H11N3SHCl and molecular weight 229.73 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Methyl-N-(thiophen-2-ylmethyl)-1H-pyrazol-4-amine hydrochloride (C9H11N3SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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 1-Methyl-N-(thiophen-2-ylmethyl)-1H-pyrazol-4-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.
