Description
Perfluorotributylamine (PFTBA, also termed FC-43) is a common mass calibrant used in GC-MS systems. It is a dense, moderately high-boiling liquid. It is the main component of Fluosol-43, an artificial blood substitute that has been approved by the US Food and Drug Administration for use in cardiac angioplasty. PFTBA is also used as an ingredient in some refrigerants. It is persistent in the atmosphere and a powerful greenhouse gas. In 2013, S. A. Mabury at the University of Toronto used IR spectroscopy data to calculate that PFTBA is the strongest global-warming potential of any compound detected in the atmosphere-7100 times greater than that of CO2.
Chemical Properties
clear colourless liquid
Uses
Perfluorotributylamine is used in electronic applications viz. liquid burn-in, testing and vapor phase soldering processes. It acts as an indicator fluid to check the leakage and heat transfer fluid for thermal shock testing. It is an active component in fluosol, which is a substitute for artificial blood and fluorinert coolant liquids. Further, it is used as a solvent for computer disc drive lubrication. In addition to this, it is used as a calibration chemical in gas chromatography.Perfluorotributylamine (PFTBA) is commonly used for the calibration of the mass axes of mass spectrometers, basically in those systems, which use electron ionization (EI). PFTBA may be used as a calibration standard for the gas chromatography-mass spectrometric determination of tramadol in human plasma samples and phthalate esters in water samples.
Definition
ChEBI: Perfluorotributylamine is an organofluorine compound that is tributylamine in which all the hydrogens have been replaced by fluorine atoms. It has a role as a member of greenhouse gas, a solvent and a blood substitute. It derives from a tributylamine.
Precautions
Store in a cool place. Incompatible with powdered metals and alkali metals.
Check Digit Verification of cas no
The CAS Registry Mumber 311-89-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,1 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 311-89:
(5*3)+(4*1)+(3*1)+(2*8)+(1*9)=47
47 % 10 = 7
So 311-89-7 is a valid CAS Registry Number.

An efficient high-yield synthesis for perfluorinated tertiary alkyl amines
Felling, Kyle W.,Lagow, Richard J.
, p. 233 - 236 (2003)
We wish to report a high-yield synthesis of perfluorinated tertiary amines from their hydrocarbon analogues by direct fluorination. Yields up to 70%, with high purities, have been obtained from certain tertiary amines. This technique will likely develop into a new general method for producing perfluorinated amines.
Technology for the preparation of perfluoro-organic compounds
Moldavskii, Dmitrii D.,Bispen, Tatjana A.,Kaurova, Galina I.,Furin, Georgii G.
, p. 157 - 167 (2007/10/03)
Fluorination by elemental fluorine of fluorine-containing alkenes, alkanes, ethers and tertiary amines was investigated, aimed at obtaining the perfluorinated analogs. The factors affecting yield of the target compounds were studied. Elements of technology were elucidated.
