Chemical Structure
Description
Based on its molecular formula C6H9ClNO5P, 4-Chloro-5-methyliSoxazol-3-yl dimethyl phosphate contains a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 241.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 4-Chloro-5-methyliSoxazol-3-yl dimethyl phosphate (CAS 32306-32-4), a certified reference material (molecular formula C6H9ClNO5P, MW 241.57 g/mol) for analytical method development and quality control.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
