DescriptionBiotin, also known as D-biotin or biotin ratiopharm, belongs to the class of organic compounds known as biotin and derivatives. These are organic compounds containing a ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring. Biotin is an extremely weak basic (essentially neutral) compound (based on its pKa). Biotin exists in all living species, ranging from bacteria to humans. Biotin is a potentially toxic compound.
