Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Omethoate-d3.
Omethoate-d3 (CAS 1189510-77-7), molecular formula C5H9D3NO4PS and molecular weight 216.21 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H9D3NO4PS, Omethoate-d3 contains deuterium isotope labeling, a carbohydrate-derived structure, an amide group, a sulfone group, a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 216.21 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.
