2,2,6,6-Tetramethylpiperidinooxy/TEMPO with Cas 2564-83-2

2,2,6,6-tetramethylpiperidine oxide (TEMPO) is a non-metallic organic catalyst widely used in organic synthesis, material modification, and environmental remediation. It has high selectivity, mild reaction conditions, and green environmental protection characteristics.

‌

Organic synthesis and oxidation reactions:

TEMPO can oxidize primary alcohols to aldehydes and secondary alcohols to ketones under mild conditions, with high reaction selectivity and few by-products. For example, in the synthesis of pharmaceutical intermediates, it is used to convert alpha hydroxy esters into ketone compounds, improving the purity of drug precursors.

‌

Material modification and polymer processing:

In the field of materials, TEMPO is used for cellulose modification, polymer chain regulation, and functionalization of polymer materials. For example, introducing carbonyl functional groups through the oxidation of polyvinyl alcohol (PVA) can improve the subsequent reaction performance of the material.

‌

Environmental governance and wastewater treatment:

TEMPO can promote the degradation of organic pollutants and achieve the oxidative decomposition of difficult to degrade substances in wastewater treatment, which meets green chemistry standards.

‌

Pharmaceuticals and Biomaterials:

Its derivatives are used for the preparation of key intermediates in drug synthesis, improving process safety and product purity; In biomaterial modification, biocompatibility and functionality can be improved.
