Description
CATO manufactures Ethylphosphonic dichloride 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.
Ethylphosphonic dichloride (CAS 1066-50-8), molecular formula C2H5Cl2OP and molecular weight 146.94 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C2H5Cl2OP, Ethylphosphonic dichloride contains organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 146.94 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
