Chemical Structure
Description
(S)-Benzyl (1-(2-chloroacetyl)pyrrolidin-3-yl)(cyclopropyl)carbamate (C17H21ClN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
(S)-Benzyl (1-(2-chloroacetyl)pyrrolidin-3-yl)(cyclopropyl)carbamate (CAS 1353993-52-8), molecular formula C17H21ClN2O3 and molecular weight 336.81 g/mol, is a CATO reference standard with documented purity and traceability.
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.
