Chemical Structure
Description
3-Chloro-5,6,7,8-tetrahydroimidazo[1,5-a]pyrazine hydrochloride (CAS 2089315-28-4) is a high-purity analytical reference standard with the molecular formula C6H8ClN3HCl and a molecular weight of 194.06 g/mol.
3-Chloro-5,6,7,8-tetrahydroimidazo[1,5-a]pyrazine hydrochloride (C6H8ClN3HCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
