Dibutyl squarate explained
Dibutyl squarate (also known as squaric acid dibutyl ester or SADBE) is a chemical compound with the molecular formula C12H18O4. It is the dibutyl derivative of squaric acid.
Medically, it is used for the treatment of warts[1] and for treating alopecia areata or alopecia totalis (autoimmune hair loss) through topical immunotherapy involving the production of an allergic rash.[2] [3] Dibutyl squarate is currently undergoing trials for use in treating herpes labialis (cold sores).[4]
