Chemical Structure
Description
(S)-tert-Butyl 6-bromo-1-((R)-1,1-dimethylethylsulfinamido)-1,3-dihydrospiro[indene-2,4'-piperidine]-1'-carboxylate (CAS 2377355-25-2) is a high-purity analytical reference standard with the molecular formula C22H33BrN2O3S and a molecular weight of 485.48 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, (S)-tert-Butyl 6-bromo-1-((R)-1,1-dimethylethylsulfinamido)-1,3-dihydrospiro[indene-2,4'-piperidine]-1'-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 485.48 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.
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.
