Description

The occurrence of 1,3-Dimethyl-3,4-dihydro-1H-1,4-benzodiazepine-2,5-dione is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3-Dimethyl-3,4-dihydro-1H-1,4-benzodiazepine-2,5-dione (CAS 5973-23-9) is a high-purity analytical reference standard with the molecular formula C11H12N2O2 and a molecular weight of 204.23 g/mol.

1,3-Dimethyl-3,4-dihydro-1H-1,4-benzodiazepine-2,5-dione (C11H12N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. 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.

As a certified reference material (CRM), 1,3-Dimethyl-3,4-dihydro-1H-1,4-benzodiazepine-2,5-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
