Chemical Structure

7-oxooxepane-4-carboxylic acid CAS 485817-06-9 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 7-oxooxepane-4-carboxylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.15 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).

7-oxooxepane-4-carboxylic acid (CAS 485817-06-9) is a high-purity analytical reference standard with the molecular formula C7H10O4 and a molecular weight of 158.15 g/mol.

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.

CATO manufactures 7-oxooxepane-4-carboxylic 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.
