Product information
Theta-cypermethrin is stable as a solid but it is readily hydrolysed in alkaline solution. Its half-lives at pH values 3,7 and 9 (25 °C) were 50,20 and 10 days (PM). By analogy with cypermethrin, the rate-determining step in dilute solution is nucleophilic attack by OH-. Half-lives of transcypermethrin in river water and sea water at 25 °C were 5 and 7 days, respectively. Major products were 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid (2, DCVA), 3-phenoxybenzaldehyde (9, 3PBAl) and a-carbamoyl-3-phenoxybenzyl 3-(2,2-dichlorovinyl)-2,2- dimethylcyclopropanecarboxylate (the amide 3); minor products were the a-carboxy analogue of 3 (4) and 3-phenoxybenzoic acid (10,3PBA) (see cypermethrin, Schemes la and 1b).
Photodecomposition would be expected to be similar to that of cypermethrin.
