Chemical Structure

Benzylidenehydrazine CAS 5281-18-5 chemical structure

Description

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

Benzylidenehydrazine (CAS 5281-18-5), molecular formula C7H8N2 and molecular weight 120.15 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, an aromatic ring system, Benzylidenehydrazine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
