1-(2-(4-(Tert-butyl)phenyl)-1h-indol-3-yl)-2-chloroethan-1-one CAS 924255-82-3 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 1-(2-(4-(Tert-butyl)phenyl)-1h-indol-3-yl)-2-chloroethan-1-one.

1-(2-(4-(Tert-butyl)phenyl)-1h-indol-3-yl)-2-chloroethan-1-one (CAS 924255-82-3) is a high-purity analytical reference standard with the molecular formula C20H20ClNO and a molecular weight of 325.83 g/mol.

The molecular framework of 1-(2-(4-(Tert-butyl)phenyl)-1h-indol-3-yl)-2-chloroethan-1-one (C20H20ClNO) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 1-(2-(4-(Tert-butyl)phenyl)-1h-indol-3-yl)-2-chloroethan-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
