Chemical Structure
Description
The occurrence of 6-Methoxy-5-methyl-2,3-dihydro-1H-inden-1-one 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 6-Methoxy-5-methyl-2,3-dihydro-1H-inden-1-one (CAS 1685-77-4), a certified reference material (molecular formula C11H12O2, MW 176.21 g/mol) for analytical method development and quality control.
6-Methoxy-5-methyl-2,3-dihydro-1H-inden-1-one (C11H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 6-Methoxy-5-methyl-2,3-dihydro-1H-inden-1-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.
