Chemical Structure
Description
n-[2-(1h-indol-3-yl)ethyl]benzenesulfonamide (CAS 32585-54-9), molecular formula C16H16N2O2S and molecular weight 300.38 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H16N2O2S, n-[2-(1h-indol-3-yl)ethyl]benzenesulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), n-[2-(1h-indol-3-yl)ethyl]benzenesulfonamide 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.
