Choline-d13 (chloride) is a deuterium-labeled form of Choline chloride, which is an organic compound and a quaternary ammonium salt. It serves as an acyl group acceptor and a choline acetyltransferase substrate. Choline chloride is also utilized as an important feed additive, particularly for chickens, where it promotes growth.
Can be used as a tracer
Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
Stable heavy isotopes have been incorporated into drug molecules for quantitation during drug development
Deuteration has potential to affect pharmacokinetic and metabolic profiles of drugs
