Chemical Structure
Description
CATO supplies tert-Butyl (2-(dimethylphosphoryl)-4-(methylsulfonyl)phenyl)carbamate (CAS 2903924-13-8), a certified reference material (molecular formula C14H22NO5PS, MW 347.37 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl (2-(dimethylphosphoryl)-4-(methylsulfonyl)phenyl)carbamate (C14H22NO5PS) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 347.37 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
