(4-Carboxybutyl-d4)triphenylphosphonium (bromide)

(4-Carboxybutyl-d4)triphenylphosphonium (bromide) is intended for use as an internal standard for the quantification of (4-carboxybutyl)triphenylphosphonium by GC- or LC-MS. (4-Carboxybutyl)triphenylphosphonium is a Wittig reagent. It has been used in the synthesis of prostaglandin F2alpha (PGF2alpha, Cay-16010) and the monounsaturated fatty acid 7-methyl-6-octadecenoic acid. (4-Carboxybutyl)triphenylphosphonium has also been used to enhance mitochondrial localization of albumin nanoparticles loaded with the anticancer agent docetaxel (Cay-11637).Formal Name: (4-carboxybutyl-2,2,3,3-d4)triphenyl-phosphonium, monobromide.
