Description General description The structure of phenothiazine is rigid, being tricyclic. It is known to alter dopamine (3,4-dihydroxyphenethylamine). Its use as an electron donor is based on its unique hole transporting ability, electron releasing nitrogen and sulfur heteroatoms and its non-planar structure leading to lower molecular aggregation. Application Phenothiazine finds uses in metal free organic dye sensitizers, dyes and antioxidants. Packaging 1 kg in poly bottle 50, 250 g in glass bottle
