Compared with other compounds in its class, the molecular weight of 331.69 g/mol gives 4-Chloro-5-phenyliSoxazol-3-yl diethyl phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-5-phenyliSoxazol-3-yl diethyl phosphate (CAS 32306-30-2) is a high-purity analytical reference standard with the molecular formula C13H15ClNO5P and a molecular weight of 331.69 g/mol.
4-Chloro-5-phenyliSoxazol-3-yl diethyl phosphate (C13H15ClNO5P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 4-Chloro-5-phenyliSoxazol-3-yl diethyl phosphate 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.
