Chemical Structure

2-Oxocyclobutanecarboxylic acid CAS 52903-57-8 chemical structure

Description

CATO manufactures 2-Oxocyclobutanecarboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

2-Oxocyclobutanecarboxylic acid (CAS 52903-57-8), molecular formula C5H6O3 and molecular weight 114.10 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Oxocyclobutanecarboxylic acid (C5H6O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 114.10 g/mol, it falls into the low-molecular-weight range. 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).

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.
