Chemical Structure

1,2-Phenylenediamine CAS 95-54-5 chemical structure

Description

The occurrence of 1,2-Phenylenediamine is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,2-Phenylenediamine (CAS 95-54-5), a certified reference material (molecular formula C6H8N2, MW 108.14 g/mol) for analytical method development and quality control.

1,2-Phenylenediamine (C6H8N2) contains a nitrile group, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
