Chemical Structure
Description
(S)-2,3,4,6,7,11b-hexahydro-1H-pyrazino[2,1-a]isoquinoline dihydrochloride (CAS 5374-19-6), molecular formula C12H16N2HCl and molecular weight 224.73 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (S)-2,3,4,6,7,11b-hexahydro-1H-pyrazino[2,1-a]isoquinoline dihydrochloride (C12H16N2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 224.73 g/mol, it falls into the medium-molecular-weight range. 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.
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.
