Description

Hydrogen fluoride pyridine complex is used to prepare beta-fluoroamines via reaction with amino alcohols. As a fluorinating agent, is involved in the fluorination of 2,2-diary-1,3-dithiolanes. It is associated with nitrosonium tetrafluorborate to prepare gem-difluorides by reacting with ketoximes. It is also used to convert secondary and tertiary alcohols into their respective alkyl fluorides.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
