PANA (N-Phenyl-1-Naphthylamine) is primarily used as an anti-oxidant in jet engine lubricants, with end uses in commercial and military aircraft and other turbine engines. It is also used in greases, lubricating oils and rubber. PANA is an intermediate for production of alternative anti-oxidants.

Sulfanilic acid is used as an intermediate to make higher value-added products. Industrial applications for sulfanilic acid include its use for the production of paper brighteners, concrete additives, food dyes, and pharmaceuticals.
