Chemical Structure

Diazepam Impurity 11 CAS 5606-40-6 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, Diazepam Impurity 11 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Diazepam Impurity 11 (CAS 5606-40-6), a certified reference material (molecular formula C14H13ClN2, MW 244.72 g/mol) for analytical method development and quality control.

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.
