Chemical Structure

m-Toluidine-d9 CAS 352431-22-2 chemical structure

Description

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.

m-Toluidine-d9 (CAS 352431-22-2), molecular formula C7D9N and molecular weight 116.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of m-Toluidine-d9 (C7D9N) 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).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
