2-(11-Oxo-6,11-dihydrodibenzo[b,e]oxepin-3-yl)acetic acid CAS 55689-65-1 chemical structure

Description

The occurrence of 2-(11-Oxo-6,11-dihydrodibenzo[b,e]oxepin-3-yl)acetic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(11-Oxo-6,11-dihydrodibenzo[b,e]oxepin-3-yl)acetic acid (CAS 55689-65-1), molecular formula C16H12O4 and molecular weight 268.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2-(11-Oxo-6,11-dihydrodibenzo[b,e]oxepin-3-yl)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.26 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).

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), 2-(11-Oxo-6,11-dihydrodibenzo[b,e]oxepin-3-yl)acetic 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.
