Chemical Structure
Description
The occurrence of 2-Chloro-3-methylbutanenitrile is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-3-methylbutanenitrile (CAS 70477-21-3) is a high-purity analytical reference standard with the molecular formula C5H8ClN and a molecular weight of 117.58 g/mol.
Owing to a nitrile group, chlorine substitution, 2-Chloro-3-methylbutanenitrile is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 117.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 2-Chloro-3-methylbutanenitrile 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.
