Chemical Structure
Description
18-Bromo-6,9-octadecadiene (CAS 4102-60-7) is a high-purity analytical reference standard with the molecular formula C18H33Br and a molecular weight of 329.36 g/mol.
The molecular framework of 18-Bromo-6,9-octadecadiene (C18H33Br) is characterized by 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.
As a certified reference material (CRM), 18-Bromo-6,9-octadecadiene 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.
