Chemical Structure

4-Chlor-3-methyl-crotononitril 4-Chloro-3-methy-2-butenenitrile 4450-34-4 CAS 4450-34-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chlor-3-methyl-crotononitril 4-Chloro-3-methy-2-butenenitrile 4450-34-4.

4-Chlor-3-methyl-crotononitril 4-Chloro-3-methy-2-butenenitrile 4450-34-4 (CAS 4450-34-4), molecular formula C5H6ClN and molecular weight 115.56 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Chlor-3-methyl-crotononitril 4-Chloro-3-methy-2-butenenitrile 4450-34-4 (C5H6ClN) 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 115.56 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.

CATO manufactures 4-Chlor-3-methyl-crotononitril 4-Chloro-3-methy-2-butenenitrile 4450-34-4 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.
