The (S)-Timolol maleate, with the CAS registry number 26921-17-5, has the IUPAC name of (Z)-but-2-enedioic acid;(2S)-1-(tert-butylamino)-3-[(4-morpholin-4-yl-1,2,5-thiadiazol-3-yl)oxy]propan-2-ol. Being a kind of white to off-white powder, it is usually used as the β1-adrenergic blocker, with the product categories including Active Pharmaceutical Ingredients; Adrenoceptor.It is a beta-adrenergic antagonist similar in action to PROPRANOLOL. The levo-isomer is the more active. Timolol has been proposed as an antihypertensive, antiarrhythmic, antiangina, and antiglaucoma agent. It is also used in the treatment of MIGRAINE DISORDERS and tremor.
