General description

Dibromomethane-d2 is a deuterated NMR solvent that is useful in NMR-based research and analyses.


Dibromomethane-d2 may be used in the synthesis [18F]?uoromethylbromide-d2. This compound is used for the alkylation of N-(3,5-dichlorobenzyl)-4-hydroxybenzenecarboximidamide to form a ?uorine-18-labelled tracer that can be used in PET imaging studies.

Microchemical analysis of otolith (calcified 'ear stones' used for balance and orientation) of fishes is an important tool for studying their environmental history and management. However, the spatial resolution achieved is often too coarse to examine short-term events occurring in...
