Tofacitinib citrate Structure
Tofacitinib Chemical Structure


99% Tofacitinib citrate API is a white to off-white crystalline powder insoluble in water and ethanol but very soluble in DMSO and N, N-Dimethylacetamide.

People use tofacitinib API to treat psoriatic arthritis, moderately to severely active rheumatoid arthritis, and moderately to severely active ulcerative colitis. The latest research has shown that tofacitinib can be used for alopecia and vitiligo.

Tofacitinib binds to JAK and prevents the activation of the JAK-signal transducers and activators of the transcription (STAT) signaling pathway.

It is the first oral JAK inhibitor ever approved for ulcerative colitis by the FDA.
