| | B-PABA Usage And Synthesis |
| Biological Activity | Biotinyl-4-aminobenzoic acid (B-PABA) is used as a substrate in biotinidase assays. | | Purification Methods | Dissolve the acid in NaHCO3 solution, cool and precipitate it by adding N HCl. Collect the solid, dry it at 100o and recrystallise it from MeOH. Note that it is hydrolysed by aqueous 3M, 1M and 0.2M HCl at 120o |
