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.
2-Pyrrolidinone, 3-[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-(phenylmethyl)-, (3S)- (CAS 1956436-52-4), molecular formula C17H27NO2Si and molecular weight 305.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-Pyrrolidinone, 3-[[(1,1-dimethylethyl)dimethylsilyl]oxy]-1-(phenylmethyl)-, (3S)- is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
