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.
10-Bromo-2,3,4,6,7,11b-hexahydro-1H-pyrazino[2,1-a]isoquinoline (CAS 1188331-38-5), molecular formula C12H15BrN2 and molecular weight 267.16 g/mol, is a CATO reference standard with documented purity and traceability.
10-Bromo-2,3,4,6,7,11b-hexahydro-1H-pyrazino[2,1-a]isoquinoline (C12H15BrN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
