Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 261.66 g/mol gives 2-Chloro-3'-nitrobenzophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-3'-nitrobenzophenone (CAS 890098-19-8), molecular formula C13H8ClNO3 and molecular weight 261.66 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-3'-nitrobenzophenone (C13H8ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
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 2-Chloro-3'-nitrobenzophenone 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.
