Chemical Structure

(E)-Pent-3-en-2-one CAS 3102-33-8 chemical structure

Description

The occurrence of (E)-Pent-3-en-2-one is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-Pent-3-en-2-one (CAS 3102-33-8), a certified reference material (molecular formula C5H8O, MW 84.12 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, (E)-Pent-3-en-2-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 84.12 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.

As a certified reference material (CRM), (E)-Pent-3-en-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
