9-Bromo-2-(naphthalen-2-yl)-1'-propyl-1,10b-dihydrospiro[benzo[e]pyrazolo[1,5-c][1,3]oxazine-5,4'-piperidine] CAS 303104-42-9

Description

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.

9-Bromo-2-(naphthalen-2-yl)-1'-propyl-1,10b-dihydrospiro[benzo[e]pyrazolo[1,5-c][1,3]oxazine-5,4'-piperidine] (CAS 303104-42-9), molecular formula C27H28BrN3O and molecular weight 490.43 g/mol, is a CATO reference standard with documented purity and traceability.

9-Bromo-2-(naphthalen-2-yl)-1'-propyl-1,10b-dihydrospiro[benzo[e]pyrazolo[1,5-c][1,3]oxazine-5,4'-piperidine] (C27H28BrN3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
