Chemical Structure
Description
The occurrence of 5-Bromo-4-chloro-1H-indol-3-yl palmitate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromo-4-chloro-1H-indol-3-yl palmitate (CAS 341972-98-3), molecular formula C24H35BrClNO2 and molecular weight 484.90 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Bromo-4-chloro-1H-indol-3-yl palmitate (C24H35BrClNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Bromo-4-chloro-1H-indol-3-yl palmitate 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.
