311-89-7 Usage
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.
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.
On the electrochemical fluorination of quaternary ammonium compounds. Part 1. Tetraalkyl ammonium salts
Dimitrov. A.,Radeck, W.,Ruediger, St.,Bechstein, O.
, p. 57 - 60 (2007/10/02)
Tetraalkylated ammonium compounds, which are known to be very stable towards oxidative attack, can be electrofluorinated readily to yield perfluoro tertiary amines.Other than the enhanced formation of gaseous cleavage products, the electrofluorination proceeds similarly to that of other tertiary amines.
