(2Z)-Penten-1-yl triphenylphosphonium bromide is a phosphonium salt with the chemical formula C21H22BrP. It is a colorless solid that is soluble in organic solvents. (2Z)-penten-1-yl triphenylphosphonium bromide is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon double bonds through the Horner-Wadsworth-Emmons reaction. The (2Z)-penten-1-yl group provides a double bond with a Z-configuration, which is important for the stereochemistry of the final product. The triphenylphosphonium cation offers stability and reactivity, while the bromide anion is a common counterion in such salts. (2Z)-penten-1-yl triphenylphosphonium bromide is a valuable tool in the synthesis of various organic molecules, including pharmaceuticals and natural products, due to its ability to introduce specific functional groups and control the stereochemistry of the reaction.

Check Digit Verification of cas no

The CAS Registry Mumber 7348-79-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,4 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7348-79:
(6*7)+(5*3)+(4*4)+(3*8)+(2*7)+(1*9)=120
120 % 10 = 0
So 7348-79-0 is a valid CAS Registry Number.

Sex attractant pheromone of the pecan nut casebearer (Lepidoptera: Pyralidae)

Millar, Jocelyn G.,Knudson, Allen E.,McElfresh, J. Steven,Gries, Regine,Gries, Gerhard,Davis, James H.

, p. 331 - 339 (2007/10/03)

A female-produced sex pheromone for the pecan nut casebearer, Acrobasis nuxvorella Neunzig, has been identified from pheromone gland extracts of calling female moths. The compound (9E,11Z)-hexadecadienal [(9E,11Z)-16:Ald] was identified by coupled GC-EAD

Exo- and Endohormones. X. A Novel Route to an Isomer Mixture of 7,9-Dodecadien-1-yl Acetate Utilizable in Field Attraction of Lobesia botrana Males

Daradics, L.,Oprean, I.,Hodosan, F.

, p. 277 - 282 (2007/10/02)

Wittig condensation of (Z)-2-pentenylidene triphenylphosphorane (14) and 7-tert.-butoxy-heptanal (13) under conditions of phase transfer catalysis and subsequent conversion into the corresponding acetate afforded a mixture of 28percent 7(E),9(Z)-dodecadien-1-yl acetate, the sex pheromone of Lobesia botrana, along with the other geometrical isomers and 30percent unidentified by-products.The synthons 14 and 13 were prepared starting with (Z)-2-butene-1,4-diol (1) and hexane-1,6-diol (9), respectively.
