Description

Sulfapyridine, USP is a first generation sulfonamide antibiotic and was one of the first compounds used to treat and cure pneumonia. Sulfapyridine has also been found to have anti-inflammatory effects and can be used in immunodeficiency studies.

TOKU-E Company offers two forms of sulfapyridine: sulfapyridine, USP (S065) and sulfapyridine sodium (S106). In aqueous solution, sulfapyridine sodium is freely soluble (667 mg/mL) while sulfapyridine is significantly less soluble (0.29 mg/mL). Both forms have similar potencies and are suitable for microbiology use; however, sulfapyridine sodium is easier to work with in aqueous solution.
