Chemical Structure
Description
N-(3-Acetylthio-2-methylpropanoyl)glycine tert-Butyl Ester-d5 (CAS 1190018-72-4), molecular formula C12H16D5NO4S and molecular weight 280.40 g/mol, is a CATO reference standard with documented purity and traceability.
N-(3-Acetylthio-2-methylpropanoyl)glycine tert-Butyl Ester-d5 (C12H16D5NO4S) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
