Chemical Structure
Description
tert-Butyl (S)-(1-methyl-2,5-dioxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-3-yl)carbamate (CAS 2124261-93-2) is a high-purity analytical reference standard with the molecular formula C16H20N2O4 and a molecular weight of 304.34 g/mol.
tert-Butyl (S)-(1-methyl-2,5-dioxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-3-yl)carbamate (C16H20N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
