Application

Potassium disulfate (K 2 S 2 O 7 ) can be used: As a salt catalyst for the conversion of hemicellulose into reducing sugars such as xylose and galactose by mechanocatalysis . In the preparation of diacylbenzenes via Pd-catalyzed decarboxylative acylation of aromatic ketones with oxocarboxylic acids. As an oxidant for the preparation of monosubstituted triazoles from aryl azides and propargyl alcohol using Ag 2 O as a catalyst.

Domande frequenti

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 room temperature.

What does Reagent Grade mean?

Reagent Grade is a defined analytical purity tier suitable for general analytical and reagent applications. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Reagent Grade is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.

What does High-purity mean?

High-purity is a defined analytical purity tier suitable for general analytical and reagent applications. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. High-purity is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
