1,3-Dibenzyldihydro-1H-selenolo[3,4-d]imidazole-2,4-(3H,3aH)dione CAS 1185143-93-4

Description

Compared with other compounds in its class, the molecular weight of 385.32 g/mol gives 1,3-Dibenzyldihydro-1H-selenolo[3,4-d]imidazole-2,4-(3H,3aH)dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,3-Dibenzyldihydro-1H-selenolo[3,4-d]imidazole-2,4-(3H,3aH)dione (CAS 1185143-93-4), molecular formula C19H18N2O2Se and molecular weight 385.32 g/mol, is a CATO reference standard with documented purity and traceability.

1,3-Dibenzyldihydro-1H-selenolo[3,4-d]imidazole-2,4-(3H,3aH)dione (C19H18N2O2Se) contains a steroid core, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
