Chemical Structure

Ethyl 5-oxooctanoate CAS 5205-40-3 chemical structure

Description

CATO supplies Ethyl 5-oxooctanoate (CAS 5205-40-3), a certified reference material (molecular formula C10H18O3, MW 186.25 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 5-oxooctanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Ethyl 5-oxooctanoate 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.
