In order to provide the cyanohydrins, first sulfonic is produced which is a sediment and then by adding potassium cyanide to the sulfonic compound, the nitrile group is replaced and the compound of 4-t-butyl-2-(Npiperidinomethyl)cyanocyclohexane is obtained which had active optical chiral centers and is a new analog of active optical cyanohydrin family.
Recently, one of his major discoveries on the “Formation of the bisulfite anion (HSO3- , m/z 81) upon collision-induced dissociation of anions derived from organic sulfonic acids” was accepted for publication in the Journal of Mass Spectrometry.
Perfluorohexane sulfonic acid (PFHxS), perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PENA) were detected in > 92% of participants, with other measured PFCs detected less frequently.

FDA thus concluded that homotaurine is not an "amino acid" under Section 201(ff)(l)(D) because it is a gamma-amino sulfonic acid, and not an alpha-amino carboxylic acid or a constituent of proteins.
Nelson and colleagues from Boston University School of Public Health (Massachusetts, USA) studied the association between serum cholesterol levels and four PFCs: perfluorooctanoic acid (PFOA, C8), perfluorononanoic acid (PFNA), perfluorooctanesulfonic acid (PFOS), and perfluorohexane sulfonic acid (PFHxS).
Due to synergistic effect, the ATBS-modified PUD is expected to exhibit the benefits of both the systems and presence of sulfonic acid groups would result in a strong polyelectrolyte character.
During the study, researchers analysed the relationship between serum concentrations of four PFCs-perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorooctane sulfonic acid (PFOS) and perfluorohexane sulfonic acid (PFHxS)-and measures of cholesterol, body size and insulin resistance.
