Both Benzenesulfonamide and sulfanilamide are organic antibacterial compounds differing only in the addition of an extra amino group in sulfanilamide. The closely related compounds can be separated on a mixed-mode Primesep D column by hydrophobic and anion-exchange mechanisms or Primesep 100 column by hydrophobic and cation-exchange mechanisms with the elution order reversed using identical mobile phases. UV Detection at 230nm.

Application Column

Primesep 100

The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.

Separation of Sulfonamides and Phenylhydrazine by Mixed-Mode HPLC

May 5, 2005

Primesep 100 separates a mixture of sulfonamides (benzenesulfonamide, chlorobenzenesulfonamide, hydroxybenzenesulfonamide) and hydroxysulphaminophenylhydrazine by a mixture of polar and hydrophobic interactions. The stationary phase’s hydrophobic functionality provides a reversed-phase mechanism while the embedded cation-exchange group provides polar interactions. The separation method uses a mobile phase mixture of water, acetonitrile (MeCN, ACN) and trifluoracetic acid (TFA) with UV detection at 210 nm. This method is mass spec (LC/MS) and evaporative light scattering (ELSD) compatible.
