Chemical Structure
Description
The occurrence of 3-Ethyl-1-methyl-2-phenyl-1H-indole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Ethyl-1-methyl-2-phenyl-1H-indole (CAS 95503-21-2) is a high-purity analytical reference standard with the molecular formula C17H17N and a molecular weight of 235.32 g/mol.
Structurally, 3-Ethyl-1-methyl-2-phenyl-1H-indole (C17H17N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 235.32 g/mol, it falls into the medium-molecular-weight range. 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).
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), 3-Ethyl-1-methyl-2-phenyl-1H-indole 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.
