Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(5-chloro-2-methylphenyl)-4-(naphthalene-2-sulfonyl)piperazine 865548-75-0 MS-10733 (CAS 865548-75-0) is a high-purity analytical reference standard with the molecular formula C21H21ClN2O2S and a molecular weight of 400.92 g/mol.
1-(5-chloro-2-methylphenyl)-4-(naphthalene-2-sulfonyl)piperazine 865548-75-0 MS-10733 (C21H21ClN2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 1-(5-chloro-2-methylphenyl)-4-(naphthalene-2-sulfonyl)piperazine 865548-75-0 MS-10733 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.
