Chemical Structure

4-ethynyl-1-(trideuteriomethyl)pyrazole CAS 2133385-56-3 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.

4-ethynyl-1-(trideuteriomethyl)pyrazole (CAS 2133385-56-3), molecular formula C6H7D3N2 and molecular weight 113.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-ethynyl-1-(trideuteriomethyl)pyrazole (C6H7D3N2) is characterized by deuterium isotope labeling, a nitrile group, an aromatic ring system. 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.

CATO manufactures 4-ethynyl-1-(trideuteriomethyl)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.
