INTRODUCTION

Bromobenzene-d5 is a perdeuterated form of bromobenzene(C6H5Br),  meaning all five hydrogen atoms in the benzene ring are replaced with deuterium (a stable isotope of hydrogen with one proton and one neutron). It is used as a stable isotope labeled compound, primarily in electronics industry, specifically in the production of OLED displays, in research applications, particularly in NMR spectroscopy and as a raw material in organic synthesis.

Manufacture

It is typically synthesized by reacting benzene-d6 with bromine in the presence of a Lewis acid catalyst, such as iron(III) bromide. The reaction proceeds via electrophilic aromatic substitution, where a bromine atom replaces a deuterium atom on the benzene ring.

Applications

In OLED applications can be used for stabilization of organic molecules employed in the next generations of OLED screens, manufacturing process of semiconductors, microchips and optical fibers. It is specially used to improve the efficiency of blue pigments in OLEDs, which are often a challenge to optimize.
Besides OLEDs, Bromobenzene-d5 is also utilized in various other electronic applications and as a starting material for synthesizing other deuterated compounds.
NMR Spectroscopy
It is used in Nuclear Magnetic Resonance (NMR).Spectroscopy, primarily as a solvent or lock/reference compound particularly in high-temperature or non-polar system studies.
Mass Spectroscopy (Internal Standard)
Utilized as a stable isotope-labeled internal standard quantitative mass spectrometric methods. Deuterium labeling makes it easily distinguishable from non-labeled analytes, improving accuracy and traceability.
In Isotope labeling and tracer studies to track molecular pathways and study kinetic isotope effects.
Pharmaceutical And Chemical Research
In the development of deuterated drug candidates, especially in DMPK (drug metabolism and pharmacokinetics) studies.
