Description

Benzyl-D7 Bromide is a deuterated isotopologue of benzyl bromide, where seven hydrogen atoms are replaced by deuterium. This high isotopic purity is critical for applications requiring minimal interference from proton signals, such as in NMR spectroscopy and as an internal standard in mass spectrometry. It serves as a valuable labeled building block in pharmaceutical research, agrochemical development, and advanced material science for tracing reaction pathways and studying metabolic processes.

Application

• As a deuterated internal standard for the precise quantification of benzyl bromide or related compounds in analytical methods like GC-MS and LC-MS.
• A key labeled synthetic intermediate in the preparation of deuterated pharmaceuticals for drug metabolism and pharmacokinetics (DMPK) studies.
• Used in NMR spectroscopy as a solvent or reagent to avoid signal overlap from protonated species, enabling clearer structural analysis.
• Employed in mechanistic organic chemistry research to investigate reaction mechanisms using isotopic labeling techniques.
• Essential for synthesizing deuterated liquid crystals and other advanced materials where specific isotopic content modifies physical properties.
• Utilized in agrochemical research to create labeled pesticide analogs for environmental fate and residue analysis studies.

Quality Control

Every batch of Benzyl-D7 Bromide is produced and analyzed under strict quality protocols to ensure high chemical and isotopic purity. Our products undergo rigorous quality testing, including NMR and mass spectrometry, to confirm deuterium enrichment and chemical identity. Certificates of Analysis (COA) detailing purity, isotopic enrichment, and impurity profiles are available upon request to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its highly volatile and hygroscopic (moisture-sensitive) nature, the container should be kept tightly sealed and under an inert atmosphere for long-term storage to prevent decomposition and moisture uptake.
