Chemical Structure

o-Toluidine-d9 CAS 194423-47-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including o-Toluidine-d9.

o-Toluidine-d9 (CAS 194423-47-7) is a high-purity analytical reference standard with the molecular formula C7D9N and a molecular weight of 116.21 g/mol.

Owing to deuterium isotope labeling, a nitrile group, an aromatic ring system, o-Toluidine-d9 is typically pale yellow to yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 116.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
