Overview

Description

For a synthetic protocol using NMP initiators, contributed by Prof. Karen Wooley, please visit ourtechnology spotlight.TEMPO (2,2,6,6-Tetramethyl-1-piperidinyloxy) was used for trapping the styrenyl radical generated from benzoyl peroxide during nitroxide-mediated radical polymerization of styrene. TEMPO-mediated oxidation was employed for the carboxylation of water-resistant nanofibrillated cellulose (NFC) films.Stable nitroxide radical useful in controlling living polymerizations

Frequently Asked Questions

What is the purity of this product?

This product is supplied at ≥99% purity (chemical assay). Lot-specific values are stated on the Certificate of Analysis.

How should this product be stored?

Store at 2–8 °C. Refrigerated storage is required to maintain the specified shelf life.

What does sublimed grade mean?

sublimed grade indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.

How is this product shipped?

This product ships chilled on wet ice. Unpack on arrival and transfer it to the storage condition stated above.

What are the CAS number, molecular formula and molecular weight?

The CAS Number is 2564-83-2, the molecular formula is C9H18NO, and the molecular weight is 156.25 g/mol. InChIKey QYTDEUPAUMOIOP-UHFFFAOYSA-N.
