Specification
Eicosafluoroundecanoic acid with cas registry number of 1765-48-6 is also known as 11H-perfluoroundecanoic acid ; 11H-eicosafluoroundecanoic acid ; 11H pfunda ; 11eicosafluoroundecanoicacid ; 11-H-eicosafluorundekansaeure ; 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11-Eicosafluoro-undecanoicaci ; 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11-Eicosafluoroundecanoicacid ; Eicosafluoroundecanoicacid . It is a white solid and it is insoluble in water. It is stable under normal temperatures and pressures but it also should be stored in a tightly closed container when not in use and stored in a cool, dry place. Eicosafluoroundecanoic acid is used as an intermediate in synthesis of many useful compounds.
