Chemical Structure

2,2'-(Ethene-1,2-diyl)bis(benzo[d]oxazole-5-carboxylic acid) CAS 67668-97-7 chemical structure

Description

The occurrence of 2,2'-(Ethene-1,2-diyl)bis(benzo[d]oxazole-5-carboxylic acid) is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,2'-(Ethene-1,2-diyl)bis(benzo[d]oxazole-5-carboxylic acid) (CAS 67668-97-7), a certified reference material (molecular formula C18H10N2O6, MW 350.28 g/mol) for analytical method development and quality control.

Structurally, 2,2'-(Ethene-1,2-diyl)bis(benzo[d]oxazole-5-carboxylic acid) (C18H10N2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 350.28 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
