Chemical Structure
Description
The occurrence of 5-Chloro-2-methyl-2,3-dihydro-1H-inden-1-one is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Chloro-2-methyl-2,3-dihydro-1H-inden-1-one (CAS 64220-40-2), a certified reference material (molecular formula C10H9ClO, MW 180.63 g/mol) for analytical method development and quality control.
5-Chloro-2-methyl-2,3-dihydro-1H-inden-1-one (C10H9ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Chloro-2-methyl-2,3-dihydro-1H-inden-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
