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.
[S-(R,R)]-[1-[(Methoxyamino)carbonyl]-2-[(methylsulfonyl)oxy]propyl]-carbamic Acid 1,1-Dimethylethyl Ester (CAS 80575-79-7) is a high-purity analytical reference standard with the molecular formula C11H22N2O7S and a molecular weight of 326.37 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, [S-(R,R)]-[1-[(Methoxyamino)carbonyl]-2-[(methylsulfonyl)oxy]propyl]-carbamic Acid 1,1-Dimethylethyl Ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
