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.
1-Benzyl-2-oxo-2,3-dihydro-1H-indol-3-yl N-(3-chlorophenyl)carbamate (CAS 400076-65-5) is a high-purity analytical reference standard with the molecular formula C22H17ClN2O3 and a molecular weight of 392.83 g/mol.
1-Benzyl-2-oxo-2,3-dihydro-1H-indol-3-yl N-(3-chlorophenyl)carbamate (C22H17ClN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
As a certified reference material (CRM), 1-Benzyl-2-oxo-2,3-dihydro-1H-indol-3-yl N-(3-chlorophenyl)carbamate 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.
