Chemical Structure

3-vinyl-1H-pyrazole CAS 56342-52-0 chemical structure

Description

CATO manufactures 3-vinyl-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.

3-vinyl-1H-pyrazole (CAS 56342-52-0), molecular formula C5H10N2 and molecular weight 98.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-vinyl-1H-pyrazole (C5H10N2) 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.
