Hydroquinone-d6 | CAS 71589-26-9

OVERVIEW  of  Hydroquinone-d6 | CAS 71589-26-9

Hydroquinone-d6 (CAS 71589-26-9) is a fully deuterated form of hydroquinone, where all six hydrogen atoms on the aromatic ring are replaced with deuterium. This isotopic substitution significantly enhances its performance as an internal standard in analytical methods, offering improved mass differentiation, reduced matrix interference, and higher quantitative accuracy. Because hydroquinone is a widely monitored oxidative metabolite and environmental analyte, its deuterium-labelled counterpart is essential for robust analytical workflows in research and regulated testing environments.
