CAS 41891-54-7: triethyl 3-methyl-4-phosphono-2-buten-oate (cis+trans)

Description: Triethyl 3-methyl-4-phosphono-2-buten-oate, with the CAS number 41891-54-7, is an organophosphorus compound characterized by its ester functional groups and phosphonate moiety. This substance typically exists as a mixture of cis and trans isomers, which can exhibit different physical and chemical properties due to the spatial arrangement of atoms around the double bond. It is a colorless to pale yellow liquid with a distinctive odor, soluble in organic solvents but less so in water. The compound is known for its applications in agricultural chemistry, particularly as a pesticide or herbicide, owing to its ability to inhibit certain enzymes in target organisms. Its structure includes a phosphonate group, which contributes to its reactivity and potential biological activity. Safety considerations are important when handling this compound, as it may pose risks associated with organophosphorus compounds, including toxicity to non-target organisms. Proper storage and handling protocols should be followed to mitigate any hazards.
