Description
3,3'-(Ethane-1,2-diylbis(sulfanediyl))bis(3-(4-chlorophenyl)-1-(4-methoxyphenyl)propan-1-one) (CAS 329779-52-4), molecular formula C34H32Cl2O4S2 and molecular weight 639.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 3,3'-(Ethane-1,2-diylbis(sulfanediyl))bis(3-(4-chlorophenyl)-1-(4-methoxyphenyl)propan-1-one) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 639.65 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.
CATO manufactures 3,3'-(Ethane-1,2-diylbis(sulfanediyl))bis(3-(4-chlorophenyl)-1-(4-methoxyphenyl)propan-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.
