Description
Chloromethane-D₃ (D, 99%) is used as a specialized deuterated methylating agent in the synthesis of labeled active pharmaceutical ingredients (APIs). It introduces a stable trideuteromethyl group (-CD₃) into drug molecules to create deuterium-labeled analogs. These labeled compounds serve as internal standards for bioanalytical quantification, mass spectrometry (LC-MS/MS) assays, and pharmacokinetic drug metabolism studies.
