Description
Trifluoro(methanol)boron, also known as Boron trifluoride-methanol (BF-M), is a colorless to amber solution that serves as a powerful acidic catalyst. It is an esterification reagent with the ability to cleave acetylated dyes, resulting in free amino groups. Trifluoro(methanol)boron is known for its versatility in various applications across different industries.
Uses
Used in Gas Chromatography (GC) Analysis:
Trifluoro(methanol)boron is used as a reagent for the GC analysis of ritalinic acid, providing an alternative to Cl2CHCO2H for the synthesis of purine-rich oligomers.
Used in Organic Synthesis:
As a Lewis acid, Trifluoro(methanol)boron is utilized in the preparation of geminal bis-peroxides from ketals and enol ethers with t-butyl hydroperoxide, facilitating the formation of these complex molecules.
Used in Pharmaceutical Industry:
Trifluoro(methanol)boron is employed as a reagent for the mild deacetylation of amines, which is a crucial step in the synthesis of various pharmaceutical compounds.
Used in Lipid Analysis:
It is used in the transmethylation of 1,2-Diacylglycerol (DAG) containing fractions, which are purified using High-Performance Liquid Chromatography (HPLC). This process is essential for treating lipids during GC analysis for the determination of fatty acid methyl esters and dimethylacetals.
Used in Biodiesel Production:
Trifluoro(methanol)boron is used as a catalyst in the trans esterification of vegetable oils to form biodiesel, a renewable and environmentally friendly fuel source.
Check Digit Verification of cas no
The CAS Registry Mumber 373-57-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 373-57:
(5*3)+(4*7)+(3*3)+(2*5)+(1*7)=69
69 % 10 = 9
So 373-57-9 is a valid CAS Registry Number.
