Application:
2-(Chloromethyl)-4-Methylquinazoline (CAS: 109113-72-6) is used as an intermediate for the preparation of Linagliptin (CAS: 668270-12-0), and its impurities. Linagliptin, sold under the brand name Tradjenta among others, is a medication used to treat diabetes mellitus type 2. It is generally less preferred than metformin and sulfonylureas as an initial treatment. It is used together with exercise and diet. It is not recommended in type 1 diabetes. It works by increasing the production of insulin and decreasing the production of glucagon by the pancreas. Linagliptin was approved for medical use in the United States in 2011. Linagliptin is a highly potent, selective dipeptidyl peptidase-4 (DPP-4) inhibitor with IC50 of 1 nM.
