Chemical Structure

hex-5-ynoyl chloride CAS 55183-45-4 chemical structure

Description

CATO manufactures hex-5-ynoyl 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.

hex-5-ynoyl chloride (CAS 55183-45-4), molecular formula C6H7ClO and molecular weight 130.57 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, hex-5-ynoyl chloride (C6H7ClO) contains a hydroxyl group, an ether linkage, 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 130.57 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.
