Description

CAS: 2564-83-2 | C9H18NO | 156.25 g/mol

TEMPO is used as a catalyst in organic synthesis and for the oxidation of primary alcohols to aldehydes. It finds use in the chemical industry for conversion of bisnoralcohol (a steroid) to bisnoraldehyde. It acts as a free radical scavenger, as a mediator in controlled radical polymerization and as a structural probe in electron spin resonance spectroscopy. Further, it is involved in the preparation of (S)-(+)-2-methylbutanal from (S)-(-)-2-methyl-1-butanol.

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.
