2,2-Dimethyl-3-((2-oxodihydrofuran-3(2H)-ylidene)methyl)cyclopropanecarboxylic acid CAS 790612-67-8 chemical structure

Description

The occurrence of 2,2-Dimethyl-3-((2-oxodihydrofuran-3(2H)-ylidene)methyl)cyclopropanecarboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,2-Dimethyl-3-((2-oxodihydrofuran-3(2H)-ylidene)methyl)cyclopropanecarboxylic acid (CAS 790612-67-8), a certified reference material (molecular formula C11H14O4, MW 210.23 g/mol) for analytical method development and quality control.

Structurally, 2,2-Dimethyl-3-((2-oxodihydrofuran-3(2H)-ylidene)methyl)cyclopropanecarboxylic acid (C11H14O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 210.23 g/mol, it falls into the medium-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.

As a certified reference material (CRM), 2,2-Dimethyl-3-((2-oxodihydrofuran-3(2H)-ylidene)methyl)cyclopropanecarboxylic 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.
