Chemical Structure

Butyl (E)-2-butenoate CAS 591-63-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 142.20 g/mol gives Butyl (E)-2-butenoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Butyl (E)-2-butenoate (CAS 591-63-9), a certified reference material (molecular formula C8H14O2, MW 142.20 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Butyl (E)-2-butenoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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

As a certified reference material (CRM), Butyl (E)-2-butenoate 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.
