Chemical Structure

40876-94-6 1-Ethyl-2-methyl-1H-indole 1H-Indole, 1-ethyl-2-methyl- EINECS 255-121-3 CAS 40876-94-6 chemical structure

Description

40876-94-6 1-Ethyl-2-methyl-1H-indole 1H-Indole, 1-ethyl-2-methyl- EINECS 255-121-3 (CAS 40876-94-6) is a high-purity analytical reference standard with the molecular formula C11H21N and a molecular weight of 167.29 g/mol.

The molecular framework of 40876-94-6 1-Ethyl-2-methyl-1H-indole 1H-Indole, 1-ethyl-2-methyl- EINECS 255-121-3 (C11H21N) is characterized by a nitrile group. 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 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), 40876-94-6 1-Ethyl-2-methyl-1H-indole 1H-Indole, 1-ethyl-2-methyl- EINECS 255-121-3 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.
