Description

Benzoyl-D5 Chloride CAS NO 43019-90-5 is a deuterated isotopologue of benzoyl chloride, where five hydrogen atoms are replaced with deuterium. This deuteration is critical for applications requiring reduced metabolic interference and enhanced analytical precision. It is an essential building block and labeling reagent for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced material sectors.

Application

• Pharmaceutical Research & Development: Used as a deuterated precursor in the synthesis of isotopically labeled drug candidates for pharmacokinetic (ADME) studies, metabolic pathway tracing, and the development of deuterated drugs.
• Analytical Chemistry & Mass Spectrometry: Serves as a derivatization agent or internal standard for the accurate quantification of compounds via GC-MS or LC-MS, improving method sensitivity and reliability.
• Agrochemical Synthesis: Employed in the development of deuterated pesticides and herbicides to study their environmental fate, degradation pathways, and biological activity.
• Organic Synthesis & Material Science: Acts as a key reagent for introducing the benzoyl-D5 moiety into complex molecules, polymers, and advanced materials for research purposes.
• NMR Spectroscopy: Useful as a solvent or reagent in deuterated form to avoid proton signal interference in nuclear magnetic resonance analysis.
