Chemical Structure

4-Amino-1-ethyl-3,5-dimethyl-1H-pyrazole CAS 63203-90-7 chemical structure

Description

4-Amino-1-ethyl-3,5-dimethyl-1H-pyrazole (CAS 63203-90-7) is a high-purity analytical reference standard with the molecular formula C7H13N3 and a molecular weight of 139.20 g/mol.

The molecular framework of 4-Amino-1-ethyl-3,5-dimethyl-1H-pyrazole (C7H13N3) 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.

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

CATO manufactures 4-Amino-1-ethyl-3,5-dimethyl-1H-pyrazole 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.
