Acrylic Acid-d4 (CAS 285138-82-1): A Deuterated Building Block for Isotope Labeling and Analytical R

Acrylic acid-d4 CAS:285138-82-1 is a deuterium-labeled analog of acrylic acid in which four hydrogen atoms are replaced by deuterium. Deuterated compounds such as acrylic acid-d4 play an important role in isotope labeling, analytical chemistry, and mechanistic studies, where precise tracking of molecular transformations is required.

Due to the presence of deuterium atoms, acrylic acid-d4 exhibits similar chemical reactivity to its non-labeled counterpart while providing distinguishable signals in spectroscopic and mass-spectrometric analyses. This property makes it a valuable tool in research areas ranging from polymer science to metabolic studies.
