Chemical Structure

3,4,5-Trimethyl-4H-1,2,4-triazole CAS 16759-45-8 chemical structure

Description

3,4,5-Trimethyl-4H-1,2,4-triazole (CAS 16759-45-8) is a high-purity analytical reference standard with the molecular formula C5H9N3 and a molecular weight of 111.15 g/mol.

The molecular framework of 3,4,5-Trimethyl-4H-1,2,4-triazole (C5H9N3) 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.

As a certified reference material (CRM), 3,4,5-Trimethyl-4H-1,2,4-triazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
