Chemical Structure
Description
The occurrence of Ethyl 5-(Benzyloxy)indole-3-acetate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 5-(Benzyloxy)indole-3-acetate (CAS 163688-25-3), a certified reference material (molecular formula C19H19NO3, MW 309.36 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 5-(Benzyloxy)indole-3-acetate (C19H19NO3) is characterized by a steroid core, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
