Chemical Structure
Description
As a certified reference material (CRM), Dimethyl (2-(benzylamino)-2,3-dihydro-1H-inden-2-yl)phosphonate 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.
CATO supplies Dimethyl (2-(benzylamino)-2,3-dihydro-1H-inden-2-yl)phosphonate (CAS 1403884-98-9), a certified reference material (molecular formula C18H22NO3P, MW 331.35 g/mol) for analytical method development and quality control.
The molecular framework of Dimethyl (2-(benzylamino)-2,3-dihydro-1H-inden-2-yl)phosphonate (C18H22NO3P) is characterized by a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
