Chemical Structure
Description
4-(2-Bromo-5-cyclohexyl-3-hydroxypent-1-en-1-yl)hexahydro-2H-cyclopenta[b]furan-2,5-diol (CAS 60057-00-3) is a high-purity analytical reference standard with the molecular formula C18H29BrO4 and a molecular weight of 389.32 g/mol.
The molecular framework of 4-(2-Bromo-5-cyclohexyl-3-hydroxypent-1-en-1-yl)hexahydro-2H-cyclopenta[b]furan-2,5-diol (C18H29BrO4) is characterized by a steroid core, a hydroxyl group, an ether linkage, 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. 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.
As a certified reference material (CRM), 4-(2-Bromo-5-cyclohexyl-3-hydroxypent-1-en-1-yl)hexahydro-2H-cyclopenta[b]furan-2,5-diol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
