Chemical Structure
Description
The occurrence of 5-(Tert-butyl)-2-cyclopentyl-1H-indole-3-carbaldehyde 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.
5-(Tert-butyl)-2-cyclopentyl-1H-indole-3-carbaldehyde (CAS 590347-39-0), molecular formula C18H23NO and molecular weight 269.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(Tert-butyl)-2-cyclopentyl-1H-indole-3-carbaldehyde (C18H23NO) 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.
CATO manufactures 5-(Tert-butyl)-2-cyclopentyl-1H-indole-3-carbaldehyde 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.
