Chemical Structure

p-Toluidine-d3 (methyl-d3) CAS 23346-25-0 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.

p-Toluidine-d3 (methyl-d3) (CAS 23346-25-0), molecular formula C7H6D3N and molecular weight 110.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of p-Toluidine-d3 (methyl-d3) (C7H6D3N) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), p-Toluidine-d3 (methyl-d3) 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.
