Medchemexpress LLC Methyl paraben-d4 | 362049-51-2 | 156.17 | 25 MG

Methyl paraben-d4 is the deuterium labeled Methyl Paraben. Methyl Paraben, isolated from the barks of Tsuga dumosa, the methyl ester of p-hydroxybenzoic acid, is a standardized chemical allergen. It is a stable, non-volatile compound used as an antimicrobial preservative in foods, agents and cosmetics. The physiologic effect of Methyl Paraben is by means of increased histamine release and cell-mediated immunity.

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 the drug development process.
Deuteration can affect the pharmacokinetic and metabolic profiles of drugs.
