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.
8-Benzyl-2-(hydroxymethyl)octahydroisoxazolo[2,3-a]pyridin-8-ium bromide (CAS 119204-20-5), molecular formula C15H22NO2Br and molecular weight 328.25 g/mol, is a CATO reference standard with documented purity and traceability.
8-Benzyl-2-(hydroxymethyl)octahydroisoxazolo[2,3-a]pyridin-8-ium bromide (C15H22NO2Br) contains a nitrogen-containing heterocyclic scaffold, 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, 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).
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.
