Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Benzyl-1,2,3,4-tetrahydroquinoxaline dihydrochloride.
1-Benzyl-1,2,3,4-tetrahydroquinoxaline dihydrochloride (CAS 2602-38-2), molecular formula C15H16N2HCl and molecular weight 260.76 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Benzyl-1,2,3,4-tetrahydroquinoxaline dihydrochloride (C15H16N2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 260.76 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.
