| 2-methyl-4-isothiazolin-3-one | A 1,2-thazole that is 4-isothiazolin-3-one bearing a methyl group on the nitrogen atom. It is a powerful biocide and preservative and is the minor active ingredient in the commercial product Kathon(TM). | methylisothiazolinone |
| 2-n-octyl-4-isothiazolin-3-one | A member of the class of 1,2-thiazole that is 1,2-thiazol-3-one substituted on the nitrogen (position 2) by an octyl group. A fungicide and antibacterial agent, it is used for treatment of canker and other fungal and bacterial diseases in fruit trees. It is no longer approved for use within the European Union. | octhilinone |
| 5-chloro-2-methyl-4-isothiazolin-3-one | A 1,2-thiazole that is 4-isothiazolin-3-one bearing a methyl group on the nitrogen atom and a chlorine at C-5. It is a powerful biocide and preservative and is the major active ingredient in the commercial product Kathon(TM). | chloromethylisothiazolinone |
| kathon 930 | A 1,2-thiazole that is 1,2-thiazol-3(2H)-one substituted by chloro groups at positions 4 and 5 and an octyl group at position 2. It is used as a fungicide. | 4,5-dichloro-2-n-octyl-3(2H)-isothiazolone |
| n-(1-methyl-5-indolyl)-n'-(3-methyl-5-isothiazolyl)urea | A member of ther class of ureas that is urea in which a hydrogen attached to one of the nitrogens has been replaced by an N-methylindol-5-yl group, while a hydrogen attached to the other nitrogen has been replaced by a 3-methyl-1,2-thiazol-5-yl group. It is a potent and selective antagonist for the 5-hydroxytryptamine 2B (5-HT2B) receptor. | 1-(1-methylindol-5-yl)-3-(3-methyl-1,2-thiazol-5-yl)urea |
