Description

α-Terpineol (Propyl Methyl-D3) is a deuterated derivative of the naturally occurring monoterpene alcohol, α-terpineol. This isotopically labeled compound is of critical importance for applications requiring precise analytical tracking and metabolic studies. It is primarily utilized by research and development laboratories in the pharmaceutical, agrochemical, and fragrance industries where deuterium labeling provides distinct advantages in mass spectrometry and NMR spectroscopy.

Application

• As an internal standard in quantitative mass spectrometry (GC-MS, LC-MS) for the accurate analysis of α-terpineol and related terpenoids.
• Use as a labeled precursor or intermediate in the synthesis of deuterated pharmaceuticals and agrochemicals for metabolism and pharmacokinetics (DMPK) studies.
• Employed in NMR spectroscopy as a probe or tracer to elucidate reaction mechanisms and metabolic pathways.
• Application in fragrance and flavor research to study the stability, release, and absorption of terpene components.
• Utilization in environmental science for tracing the environmental fate and biodegradation of terpene-based compounds.
