2-Phenylethanol-d5 is a deuterium-labeled version of 2-Phenylethanol. 2-Phenylethanol (Phenethyl alcohol), which is extracted from various organisms such as rose, carnation, hyacinth, Aleppo pine, and orange blossom, is a colorless liquid with a pleasant floral odor. It also acts as an autoantibiotic produced by the fungus *Candida albicans*. This compound is utilized as an additive in cigarettes and as a preservative in soaps due to its stability in basic conditions.
- Can be used as a tracer.
- Suitable as an internal standard for quantitative analysis by techniques like NMR, GC-MS, or LC-MS.
- Incorporation of stable heavy isotopes (like deuterium) into drug molecules is largely for quantitation during the drug development process.
- Deuteration can potentially influence the pharmacokinetic and metabolic profiles of drugs.
