Tetrahydro-2H-1,4-thiazine, Thiamorpholine - Reference Information
| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| introduction | chrysin is a natural polyphenol brass compound extracted from wood butterfly of Bignoniaceae, which is widely found in honey and propolis. Its anti-cancer, anti-inflammatory, antiviral, anti-allergic, and other activities have attracted extensive attention. However, the structure of chrysin determines that its water solubility and fat solubility are not good. Oral administration will produce serious "first pass effect", which will quickly form glucuronidation on the 5th and 7th hydroxyl groups in the body and be metabolized. Thiomorpholine can be substituted for the synthesis of base derivatives of progenitin, the structure of the 5,7 hydroxyl group of progenitin modification, so that the anticancer and antibacterial activities have been significantly improved. |
| application | thiomorpholine is soluble in methanol, acetone, benzene and ethylene glycol. Thiomorpholine is a typical secondary amine. It has the properties of inorganic acid and can form salts; it also has the properties of organic acid and can form salts and amides. Therefore, it is an important organic chemical raw material, which can be used as raw material to prepare a series of fine chemical products. 1, can be used as a vulcanization accelerator. A series of rubber vulcanization accelerators can be synthesized from thiomorpholine. 2, can be used as promoter NOBS2-(4-morpholinosyl) benzothiazole]. thiomorpholines and promoters-benzothiazole M) under the oxidation of sodium hypochlorite, the promoters NOBS2. (4-morpholinosyl) benzothiazole]. 3, can be used as a promoter NOBS. Thiomorpholine is a delayed vulcanization accelerator widely used in the rubber industry. It is mainly used in the manufacture of tires, inner tubes, rubber shoes, adhesive tapes, etc. 4. Thiomorpholine is used as a vulcanizing agent and accelerator for natural and synthetic rubber. It can improve the physical and mechanical properties and aging resistance of vulcanized rubber, and is an excellent vulcanization and accelerator. 5, thiomorpholine as anti-scorch agent. |
