WebFeb 1, 2004 · One unusual result is that β-cyfluthrin significantly reduced open channel probability, but isomers 2 and 4 (which constitute more than 90% of β-cyfluthrin; see Table 1) were individually ineffective. This implies that either one or both of the minor isomers of β-cyfluthrin caused the observed closure of chloride ion channels, or that there ... Cyfluthrin is a pyrethroid insecticide and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of isomers.

Therefore, the assumption is that the toxicity endpoints for beta-cyfluthrin should be 42% of the cyfluthrin endpoints (e.g., if the cyfluthrin endpoint is 1 mg a.i./L, than the estimated beta-cyfluthrin endpoint would be 0.42 mg a.i./L). citalopram and cannabis interactionWebFigure 7: Cyfluthrin Isomers. Cyfluthrin consists of four isomers that are not completely baseline separated with the LC gradient. The three major isomers of cyfluthrin are evident in this characteristic elution profile and all the peaks can be integrated as one component for a total sum of cyfluthrin. diana hodge obituary
