| Additional Infomation |
Fluazifop-P-butyl is a butyl 2-(4-{[5-(trifluoromethyl)pyridin-2-yl]oxy}phenoxy)propanoate that has R configutation. The active enantiomer of the herbicide fluazifop-butyl, it is used as a post-emergence herbicide for the control grass weeds in various broad-leaved crops. It has a role as an agrochemical, a herbicide and an EC 6.4.1.2 (acetyl-CoA carboxylase) inhibitor. It is functionally related to a fluazifop-P. It is an enantiomer of a (S)-fluazifop-butyl. Fluazifop-p-butyl is a selective phenoxy herbicide used for postemergence control of annual and perennial grass weeds. It is used on soybeans and other broad-leaved crops such as carrots, spinach, potatoes, and ornamentals. Fluazifop-p-butyl is a general use pesticide. Fluazifop-p-butyl is a different compound than either fluazifop or fluazifop butyl. Both the chemical structures and the toxicities of these compounds are different. Fluazifop-p-butyl formulations can contain some fluazifop-butyl. Fluazifop-p-butyl is a slightly toxic compound. A single ingested dose can cause severe stomach and intestine disturbance. Ingestion of large quantities may cause problems in the central nervous system such as drowsiness, dizziness, loss of coordination and fatigue. Breathing small amounts of the product may cause vomiting and severe lung congestion. |
Solubility Data
| Solubility (In Vitro) | DMSO: 100 mg/mL (260.85 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (6.52 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.52 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |
