Building Blocks

Stability Hygroscopic
Applications Diphenylpyraline Hydrochloride is a salt of Diphenylpyraline (D492110), an H1 receptor antagonist (an antihistamine) and is commonly prescribed to treat allergic and vasomotor rhinitis. There is also some research being conducted on diphenylpyraline derivatives to determine their antimycobacterial and antifungal activity.
