Chemical Structure

2-Methylenepentanoyl chloride CAS 78450-85-8 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 2-Methylenepentanoyl chloride.

2-Methylenepentanoyl chloride (CAS 78450-85-8), molecular formula C6H9ClO and molecular weight 132.59 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, 2-Methylenepentanoyl chloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-Methylenepentanoyl chloride 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.
