Chemical Structure

3,4-dimethylaniline hydrochloride CAS 7356-54-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 157.64 g/mol gives 3,4-dimethylaniline hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-dimethylaniline hydrochloride (CAS 7356-54-9), molecular formula C8H11NHCl and molecular weight 157.64 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,4-dimethylaniline hydrochloride (C8H11NHCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 157.64 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures 3,4-dimethylaniline hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
