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.
O,O-Dimethyl (1,3-dithiolan-2-ylidene)phosphoramidothioate (CAS 3572-55-2), molecular formula C5H10NO2PS3 and molecular weight 243.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, O,O-Dimethyl (1,3-dithiolan-2-ylidene)phosphoramidothioate (C5H10NO2PS3) contains an amide group, a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 243.31 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
