Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Acetyl-7-ethyl-1H-indol-1-yl)acetic acid.
2-(3-Acetyl-7-ethyl-1H-indol-1-yl)acetic acid (CAS 878681-51-7) is a high-purity analytical reference standard with the molecular formula C14H15NO3 and a molecular weight of 245.27 g/mol.
The molecular framework of 2-(3-Acetyl-7-ethyl-1H-indol-1-yl)acetic acid (C14H15NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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), 2-(3-Acetyl-7-ethyl-1H-indol-1-yl)acetic acid 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.
