Chemical Structure

but-2-enedinitrile CAS 17656-09-6 chemical structure

Description

The occurrence of but-2-enedinitrile is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

but-2-enedinitrile (CAS 17656-09-6), molecular formula C4H2N2 and molecular weight 78.07 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, but-2-enedinitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 78.07 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.

As a certified reference material (CRM), but-2-enedinitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
