Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Dimethyl ((2-chloroethoxy)methyl)phosphonate (CAS 126354-31-2) is a high-purity analytical reference standard with the molecular formula C5H12ClO4P and a molecular weight of 202.57 g/mol.
Dimethyl ((2-chloroethoxy)methyl)phosphonate (C5H12ClO4P) contains a carbohydrate-derived structure, a phosphate ester group, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 Dimethyl ((2-chloroethoxy)methyl)phosphonate 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.
