2-Nitrophenyloctyl ether

Succinylcholine chloride, hexamethonium bromide and decamethonium bromide were purchased from Sigma (St. Louis, MO). NPOE (2-nitrophenyloctyl ether)(Fluka) and poly(vinylchloride)(Aldrich)... 

Bisquaternary, as well as monoquaternary compounds and various amino derivatives, react with tetraphenylborate and similar compounds to form stable ion-pair complexes. TPSB was found to be very suitable as an ion-pairing agent for bisquaternary drugs with which it forms very insoluble compounds. The TPSB complexes were prepared in situ, by soaking the TPSB (potassium salt)/PVC membranes in the appropriate bisquaternary solution. Of the plasticizers tested, 2-nitrophenyloctyl ether (NPOE), dioctylphthalate, di-iso-butylphthalate, nitrobenzene, 2-nitro- -cymene, NPOE showed the best behavior in terms of response time and reproducibility. The membrane compositions were 3.2% (w/w) TPSB, 64.5% (w/w) NPOE and 32.3% (w/w) PVC. 

FAB is a relatively soft ionization technique using a high-energy (4,000- to 10,000-eV) beam of atoms, typically argon or xenon. The material to be analyzed is mixed with a nonvolatile matrix chemical. Common matrices include glycerol, thioglycerol, 3-nitrobenzyl alcohol (3-NBA), 18-crown-6 ether, 2-nitrophenyloctyl ether, sulfolane, diethanolamine, and triethanolamine.
