About heading 2928

Organic derivatives of hydrazine or of hydroxylamine

Heading 2928 covers organic derivatives of hydrazine and organic derivatives of hydroxylamine, a narrow group of nitrogen compounds used as chemical intermediates, reagents and blowing agents. The heading splits first by two specifically named compounds, methyl ethyl ketoxime and phenylhydrazine, then by whether the remaining product is aromatic, and finally by whether the non-aromatic product is a drug or another product.

Products in this heading

• Methyl ethyl ketoxime, an anti-skinning agent for paints
• Phenylhydrazine, a laboratory and dye intermediate
• p-Toluenesulfonyl hydrazide, a rubber blowing agent
