Chemical Structure
Description
The molecular framework of tert-Butyl 8-bromo-4,4-dimethyl-3,4-dihydroisoquinoline-2(1H)-carboxylate (C16H22BrNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
tert-Butyl 8-bromo-4,4-dimethyl-3,4-dihydroisoquinoline-2(1H)-carboxylate (CAS 1203682-74-9), molecular formula C16H22BrNO2 and molecular weight 340.26 g/mol, is a CATO reference standard with documented purity and traceability.
