8-(2-azidobenzylthio) NAD+ is a derivatized version of NAD+, a signaling molecule and enzyme cofactor, featuring an azido group (azidobenzylthio) that enables click chemistry applications.

Thio-NAD, a thione-modified derivative of the signaling molecule and enzyme cofactor NAD+, can substitute for NAD+ as a cofactor in alkaline phosphatase (ALP) enzyme activity assays. It is utilized as a substrate in dual-enzyme cycling ELISA for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein, or surface glycoprotein, and live M. tuberculosis in patient sputum. Thio-NAD is characterized by its absorbance at 405 nm, distinguishing it from other cofactors.

6-Biotin-17-NAD+ sodium (Biotin-LC-NAD+ sodium) is a biotinylated derivative of NAD+ and can be used to measure NADH dehydrogenase activity.
