3-Iodo-1-methyl-4,5-dihydropyrido[1,2-a][1,3]diazepine-2,7(1H,3H)-dione CAS 2222856-69-9 chemical structure

Description

The occurrence of 3-Iodo-1-methyl-4,5-dihydropyrido[1,2-a][1,3]diazepine-2,7(1H,3H)-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Iodo-1-methyl-4,5-dihydropyrido[1,2-a][1,3]diazepine-2,7(1H,3H)-dione (CAS 2222856-69-9) is a high-purity analytical reference standard with the molecular formula C10H11IN2O2 and a molecular weight of 318.11 g/mol.

3-Iodo-1-methyl-4,5-dihydropyrido[1,2-a][1,3]diazepine-2,7(1H,3H)-dione (C10H11IN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
