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.
Ethyl (5-amino-3-(4-(trifluoromethyl)phenyl)pyrido[3,4-b]pyrazin-7-yl)carbamate (CAS 83269-16-3) is a high-purity analytical reference standard with the molecular formula C17H14F3N5O2 and a molecular weight of 377.32 g/mol.
Structurally, Ethyl (5-amino-3-(4-(trifluoromethyl)phenyl)pyrido[3,4-b]pyrazin-7-yl)carbamate (C17H14F3N5O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 377.32 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
