3-Amino-5-hydroxybenzoic acid-¹³C 

3-Amino-5-hydroxybenzoic acid-¹³C is the ¹³C-labeled 3-Amino-5-hydroxybenzoic acid (HY-W077634). 3-Amino-5-hydroxybenzoic acid is a biosynthetic precursor of the mC7N unit of ansamycin antibiotics, including ansatrienin A and geldanamycin, as well as the antitumor antibiotic mitomycin C. 3-Amino-5-hydroxybenzoic acid may be an early intermediate in the shikimic acid pathway from glucose^[1][2].

1. This compound can be used as a tracer.
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs.
