3-(6-Methyl-8-oxo-3,4-dihydro-8H-spiro[cyclohexane-1,2-pyrano[3,2-g]chromen]-7-yl)propanoic acid CAS 859673-74-8 chemical structure

Description

The occurrence of 3-(6-Methyl-8-oxo-3,4-dihydro-8H-spiro[cyclohexane-1,2-pyrano[3,2-g]chromen]-7-yl)propanoic 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.

3-(6-Methyl-8-oxo-3,4-dihydro-8H-spiro[cyclohexane-1,2-pyrano[3,2-g]chromen]-7-yl)propanoic acid (CAS 859673-74-8) is a high-purity analytical reference standard with the molecular formula C21H24O5 and a molecular weight of 356.41 g/mol.

The molecular framework of 3-(6-Methyl-8-oxo-3,4-dihydro-8H-spiro[cyclohexane-1,2-pyrano[3,2-g]chromen]-7-yl)propanoic acid (C21H24O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 3-(6-Methyl-8-oxo-3,4-dihydro-8H-spiro[cyclohexane-1,2-pyrano[3,2-g]chromen]-7-yl)propanoic 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.
