311-89-7 Usage
Description
Perfluorotributylamine (PFTBA, also known as FC-43) is an organofluorine compound that is a dense, moderately high-boiling liquid. It is a derivative of tributylamine, where all hydrogen atoms have been replaced by fluorine atoms. PFTBA has a role as a greenhouse gas, a solvent, and a blood substitute. It is the main component of Fluosol-43, an artificial blood substitute approved by the US Food and Drug Administration for use in cardiac angioplasty. Additionally, it is used as an ingredient in some refrigerants and is known for its persistence in the atmosphere and powerful greenhouse gas properties.
Uses
Used in Electronic Applications:
Perfluorotributylamine is used as an indicator fluid to check for leakage and as a heat transfer fluid for thermal shock testing in electronic applications such as liquid burn-in, testing, and vapor phase soldering processes.
Used in Artificial Blood:
PFTBA is a key component in Fluosol, an artificial blood substitute that has been approved for use in cardiac angioplasty by the US Food and Drug Administration.
Used in Refrigerants:
Perfluorotributylamine is also used as an ingredient in some refrigerants, contributing to their cooling properties.
Used as a Solvent:
PFTBA serves as a solvent for computer disc drive lubrication, ensuring smooth operation and reducing wear.
Used in Gas Chromatography:
Perfluorotributylamine is utilized as a calibration chemical in gas chromatography, particularly for the calibration of mass axes of mass spectrometers that use electron ionization.
Used in Mass Spectrometry:
PFTBA is commonly used for the calibration of GC-MS systems, making it a valuable tool for accurate measurements and analysis in various fields.
Used in Environmental Analysis:
Perfluorotributylamine 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, aiding in the assessment of environmental contaminants and their impact on human health.
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.
