Chemical Structure

4-Cyclopentylbut-2-enal CAS 5662-91-9 chemical structure

Description

CATO supplies 4-Cyclopentylbut-2-enal (CAS 5662-91-9), a certified reference material (molecular formula C9H14O, MW 138.21 g/mol) for analytical method development and quality control.

Based on its molecular formula C9H14O, 4-Cyclopentylbut-2-enal contains a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 138.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 4-Cyclopentylbut-2-enal 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.
