Timolol [CAS: 26839-75-8] is a nonselective beta-adrenergic receptor blocker that treats and manages open-angle glaucoma and ocular hypertension.
Timolol: Use and Commercial Availability
Timolol treats various conditions such as ocular hypertension, angina pectoris, and the prevention of vascular headaches. It manages elevated intraocular pressure in patients with ocular hypertension or open-angle glaucoma. It also prevents migraine headaches.
Timolol is available under Betimol, Blocadren, Istalol, etc., which contain the active ingredient, Timolol.
Timolol Structure and Mechanism of Action
The chemical name of Timolol is (2S)-1-[(1,1-Dimethylethyl)amino]-3-[[4-(4-morpholinyl)-1,2,5-thiadiazol-3-yl]oxy]-2-propanol. Its chemical formula is C13H24N4O3S, and its molecular weight is approximately 316.42 g/mol.
The exact mechanism of action of Timolol is unknown.
Timolol Impurities and Synthesis
In manufacturing1 Timolol, impurity formation is possible, which impacts its effectiveness. They may originate from different sources, such as raw materials, intermediates, and chemicals for synthesizing Timolol. It is crucial to closely manage and monitor these impurities to safeguard the optimal efficacy and safety of the medication.
Daicel offers a wholesome and integrated Certificate of Analysis (CoA) for Timolol impurity standards, encompassing R-Timolol, Timolol Impurity-D, and Timolol Impurity-F. The CoA provides detailed characterization data, including 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. Additionally, we give a detailed 13C-DEPT upon delivery. With advanced technology and expertise, Daicel can synthesize any unknown Timolol impurity or degradation product. We also supply labeled compounds, facilitating the quantification of generic Timolol’s efficacy. For bioanalytical research and BA/BE studies, Daicel offers Timolol-D9 Maleate, deuterium-labeled Timolol impurity standards.
