Dimethyl Fumarate D6

Dimethyl Fumarate D6 is a fully deuterated analog of dimethyl fumarate, featuring six deuterium atoms incorporated into the trans-conjugated diene backbone. The molecule consists of a fumaric acid derivative with two methyl ester groups, where all hydrogen atoms on the double-bonded carbon chain are replaced by deuterium. This structural modification enhances its utility as a stable isotope-labeled internal standard for quantitative analysis of fumarate-based APIs via GC-MS or LC-MS/MS. Its rigid trans-configuration and ester functionality mirror the parent drug's core scaffold, enabling precise pharmacokinetic studies and impurity profiling.
