The occurrence of Ethyl 4-{[(2,3-dihydro-1H-inden-5-yl)carbamoyl]-amino}benzoate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 4-{[(2,3-dihydro-1H-inden-5-yl)carbamoyl]-amino}benzoate (CAS 893009-73-9), a certified reference material (molecular formula C19H20N2O3, MW 324.37 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 4-{[(2,3-dihydro-1H-inden-5-yl)carbamoyl]-amino}benzoate (C19H20N2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Ethyl 4-{[(2,3-dihydro-1H-inden-5-yl)carbamoyl]-amino}benzoate 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.
