Chemical Properties

LIGHT YELLOW TO BEIGE POWDER

Uses

2-Naphthalenesulfonyl chloride was employed as capping reagent for primary amine to convert histamine to a selective histamine H3-receptor antagonist. It was used for pre-column derivatization during the high-performance liquid chromatographic assay of neomycin sulfate.

Flammability and Explosibility

Not classified

Purification Methods

Distil the chloride in a vacuum and/or recrystallise it (twice) from *benzene/pet ether (1:1 v/v). Purify it as the 1-sulfonyl chloride above. [Fierz-Davaid & Weissenbach Helv Chim Acta 3 2312 1920.] The sulfonamide has m 217o (from EtOH). [Beilstein 11 III 399, 11 IV 529.]
