Description

1-Bromooctadecane-D37 is a deuterium-labeled long-chain alkyl bromide, a crucial building block in advanced chemical synthesis and analytical research. Its value lies in its isotopic purity, serving as an internal standard for mass spectrometry and enabling precise tracking in metabolic and pharmacokinetic studies. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries who require high-fidelity labeled intermediates for development and quality control.

Application

• As a deuterated internal standard for the accurate quantification of octadecyl bromide derivatives and related long-chain compounds via GC-MS or LC-MS.
• In the synthesis of deuterium-labeled surfactants, lipids, and liquid crystals for research in membrane biophysics and advanced display technologies.
• For the preparation of isotopically tagged quaternary ammonium compounds used in pharmaceutical and agrochemical studies.
• As a key intermediate in organic and organometallic synthesis, particularly in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) to create complex labeled molecules.
• In metabolic pathway tracing and drug metabolism research (DMPK) within pharmaceutical R&D.
• For the development of specialty polymers and surface modifiers where isotopic labeling is used to study material properties and interactions.
