5,6-Dimethoxy-2,3-dihydro-1H-indene-2-carboxylic acid CAS 139475-44-8 chemical structure

Description

The occurrence of 5,6-Dimethoxy-2,3-dihydro-1H-indene-2-carboxylic 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 5,6-Dimethoxy-2,3-dihydro-1H-indene-2-carboxylic acid (CAS 139475-44-8), a certified reference material (molecular formula C12H14O4, MW 222.24 g/mol) for analytical method development and quality control.

5,6-Dimethoxy-2,3-dihydro-1H-indene-2-carboxylic acid (C12H14O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 5,6-Dimethoxy-2,3-dihydro-1H-indene-2-carboxylic 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.
