Chemical Structure

2-Methylbut-3-enenitrile CAS 16529-56-9 chemical structure

Description

As a certified reference material (CRM), 2-Methylbut-3-enenitrile 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.

2-Methylbut-3-enenitrile (CAS 16529-56-9) is a high-purity analytical reference standard with the molecular formula C5H7N and a molecular weight of 81.12 g/mol.

Structurally, 2-Methylbut-3-enenitrile (C5H7N) contains a nitrile group. 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 81.12 g/mol, it falls into the low-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.
