Chemical Structure
Description
4-Ethynyl-2,3-dihydro-1H-inden-1-one (CAS 1344903-16-7), molecular formula C11H8O and molecular weight 156.18 g/mol, is a CATO reference standard with documented purity and traceability.
4-Ethynyl-2,3-dihydro-1H-inden-1-one (C11H8O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4-Ethynyl-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.
