Description
479683-64-2 A2EXW95647 CP-809101 UNII-A2EXW95647 Pyrazine, 2-((3-chlorophenyl)methoxy)-6-(1-piperazinyl)- 6'-(3-Chlorobenzyloxy)-3,4,5,6-tetrahydro-2H-(1,2')bipyrazine (CAS 479683-64-2) is a high-purity analytical reference standard with the molecular formula C15H17ClN4O and a molecular weight of 304.77 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 479683-64-2 A2EXW95647 CP-809101 UNII-A2EXW95647 Pyrazine, 2-((3-chlorophenyl)methoxy)-6-(1-piperazinyl)- 6'-(3-Chlorobenzyloxy)-3,4,5,6-tetrahydro-2H-(1,2')bipyrazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
