Chemical Structure

6-Isopropoxy-9-oxo-9H-xanthene-2-carboxylic acid CAS 33458-93-4 chemical structure

Description

The occurrence of 6-Isopropoxy-9-oxo-9H-xanthene-2-carboxylic 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.

CATO supplies 6-Isopropoxy-9-oxo-9H-xanthene-2-carboxylic acid (CAS 33458-93-4), a certified reference material (molecular formula C17H14O5, MW 298.29 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 6-Isopropoxy-9-oxo-9H-xanthene-2-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 6-Isopropoxy-9-oxo-9H-xanthene-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.
