5-Methylbenzotriazole-d6 CAS 1246820-65-4 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.

5-Methylbenzotriazole-d6 (CAS 1246820-65-4) is a high-purity analytical reference standard with the molecular formula C7HD6N3 and a molecular weight of 139.19 g/mol.

The molecular framework of 5-Methylbenzotriazole-d6 (C7HD6N3) 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.

As a certified reference material (CRM), 5-Methylbenzotriazole-d6 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.
