Sulfonic acid has a sulfur atom bonded to a carbon atom of a hydrocarbon and bonded also to three oxygen atoms, one of which has been attached to a hydrogen atom. Sulfonic acid is acidic due to the hydrogen atom, stronger than a carboxylic acid. Sulfonic acid is one of the most important organo sulfur compounds in organic synthesis.

The hydrophobic sites in α-crystallin were evaluated using a fluorescent probe 1,1′-bi(4-anilino)naphthalenesulfonic acid (bis-ANS). Approximately one binding site/subunit of α-crystallin at 25 °C was estimated by equilibrium binding and Scatchard analysis (K d = 1.1 μ m).
This test reveals the tion) and the test standard solution (containing 150 mg L 1 of D- presence of microbial oxygenase activity that produces indigo dye glucose and 150 mg L 1 of L-glutamic acid, COD = 380 mg L 1). from indole substrate (O'Connor and Hartmans, 1998).
HILIC Retention of 1,5-Naphthalenedisulfonic Acid on Obelisc N Mixed-Mode HILIC Columns. Naphthalenedisulfonic acid is retained by anion-exchange mechanism on Obelisc N mixed-mode HILIC column. Retention time is controlled by amount of ion in the mobile phase. Method demonstrates very good peak shape and controllable retention.
