Chemical Structure
Description
The occurrence of DiOC5(3) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
DiOC5(3) (CAS 53213-81-3) is a high-purity analytical reference standard with the molecular formula C27H33N2O2I and a molecular weight of 544.47 g/mol.
The molecular framework of DiOC5(3) (C27H33N2O2I) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 DiOC5(3) 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.
