Chemical Structure
Description
The occurrence of 1-Bromo-3,7,11,15-tetramethylhexadecane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-3,7,11,15-tetramethylhexadecane (CAS 2791-57-3) is a high-purity analytical reference standard with the molecular formula C20H41Br and a molecular weight of 361.44 g/mol.
The molecular framework of 1-Bromo-3,7,11,15-tetramethylhexadecane (C20H41Br) 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. 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 1-Bromo-3,7,11,15-tetramethylhexadecane 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.
