N-Ethyl-5-methyl-1H-pyrazol-3-amine CAS 116545-20-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Ethyl-5-methyl-1H-pyrazol-3-amine.

N-Ethyl-5-methyl-1H-pyrazol-3-amine (CAS 116545-20-1), molecular formula C6H11N3 and molecular weight 125.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-Ethyl-5-methyl-1H-pyrazol-3-amine (C6H11N3) is characterized by a nitrile group. 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 N-Ethyl-5-methyl-1H-pyrazol-3-amine 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.
