Chemical Structure

8-Methoxy-4-methyl-2H-benzo[g]chromen-2-one CAS 69169-71-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 240.25 g/mol gives 8-Methoxy-4-methyl-2H-benzo[g]chromen-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

8-Methoxy-4-methyl-2H-benzo[g]chromen-2-one (CAS 69169-71-7), molecular formula C15H12O3 and molecular weight 240.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 8-Methoxy-4-methyl-2H-benzo[g]chromen-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 8-Methoxy-4-methyl-2H-benzo[g]chromen-2-one 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.
