Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 4-Chloro-3,3-dimethyl-2,3-dihydro-1H-inden-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 194.66 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.
4-Chloro-3,3-dimethyl-2,3-dihydro-1H-inden-1-one (CAS 479070-71-8), molecular formula C11H11ClO and molecular weight 194.66 g/mol, is a CATO reference standard with documented purity and traceability.
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-Chloro-3,3-dimethyl-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.
