Chemical Structure
Description
Methyl hydrogen (1-diazo-2-oxopropyl)phosphonate (CAS 766475-74-5), molecular formula C4H7N2O4P and molecular weight 178.08 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H7N2O4P, Methyl hydrogen (1-diazo-2-oxopropyl)phosphonate contains a carbohydrate-derived structure, an amide group, a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 178.08 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
