Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
((2,2-Dichlorocyclopropyl)methyl)benzene (CAS 939-78-6) is a high-purity analytical reference standard with the molecular formula C10H10Cl2 and a molecular weight of 201.09 g/mol.
((2,2-Dichlorocyclopropyl)methyl)benzene (C10H10Cl2) contains 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.
CATO manufactures ((2,2-Dichlorocyclopropyl)methyl)benzene 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.
