Chemical Structure

(Z)-Pent-2-enoic acid CAS 16666-42-5 chemical structure

Description

CATO manufactures (Z)-Pent-2-enoic acid 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.

CATO supplies (Z)-Pent-2-enoic acid (CAS 16666-42-5), a certified reference material (molecular formula C5H8O2, MW 100.12 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (Z)-Pent-2-enoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 100.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
