Chemical Structure
Description
The occurrence of 2-Chloro-1-(7-ethyl-1h-indol-3-yl)-2-phenylethan-1-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Chloro-1-(7-ethyl-1h-indol-3-yl)-2-phenylethan-1-one (CAS 743441-97-6), a certified reference material (molecular formula C18H16ClNO, MW 297.78 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-1-(7-ethyl-1h-indol-3-yl)-2-phenylethan-1-one (C18H16ClNO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 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.
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.
