Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(3-Formyl-1H-indol-1-yl)-N-phenylacetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-(3-Formyl-1H-indol-1-yl)-N-phenylacetamide (CAS 333745-18-9), molecular formula C17H14N2O2 and molecular weight 278.31 g/mol, is a CATO reference standard with documented purity and traceability.
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), 2-(3-Formyl-1H-indol-1-yl)-N-phenylacetamide 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.
