Chemical Structure
Description
CATO supplies 1-(1-Naphthylmethyl)-1H-indole-2,3-dione (CAS 79183-21-4), a certified reference material (molecular formula C19H13NO2, MW 287.31 g/mol) for analytical method development and quality control.
1-(1-Naphthylmethyl)-1H-indole-2,3-dione (C19H13NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), 1-(1-Naphthylmethyl)-1H-indole-2,3-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.
