Chemical Structure

1-(5-Hydroxycyclopent-1-en-1-yl)ethanone CAS 70433-48-6 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1-(5-Hydroxycyclopent-1-en-1-yl)ethanone is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

1-(5-Hydroxycyclopent-1-en-1-yl)ethanone (CAS 70433-48-6), molecular formula C7H10O2 and molecular weight 126.15 g/mol, is a CATO reference standard with documented purity and traceability.

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), 1-(5-Hydroxycyclopent-1-en-1-yl)ethanone 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.
