Chemical Structure

3-Oxocyclobutanecarboxylic Acid CAS 23761-23-1 chemical structure

Description

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

CATO supplies 3-Oxocyclobutanecarboxylic Acid (CAS 23761-23-1), a certified reference material (molecular formula C5H6O3, MW 114.10 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Oxocyclobutanecarboxylic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 114.10 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).

As a certified reference material (CRM), 3-Oxocyclobutanecarboxylic Acid 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.
