Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (1R,2R)-1,2-Bis(4-chlorophenyl)ethane-1,2-diamine (CAS 822519-90-4), a certified reference material (molecular formula C14H14Cl2N2, MW 281.18 g/mol) for analytical method development and quality control.
(1R,2R)-1,2-Bis(4-chlorophenyl)ethane-1,2-diamine (C14H14Cl2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. 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 (1R,2R)-1,2-Bis(4-chlorophenyl)ethane-1,2-diamine 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.
