Frequently asked questions

What is 2,4-Dinitrophenylhydrazine (33% wetted material) commonly used for?

This reagent is primarily used for the detection and characterization of carbonyl compounds (aldehydes and ketones) in analytical chemistry, forming distinct hydrazone precipitates for qualitative and quantitative analysis.

What is the chemical formula and molecular weight of 2,4-Dinitrophenylhydrazine?

The formula is C₆H₆N₄O₄, and the molecular weight is 198.14 g/mol (for the anhydrous form).

How should this product be stored?

Store at 2–8°C in a cool, dry place, away from direct sunlight, heat, and incompatible substances. Keep containers tightly sealed.

What grade or purity is available for this product?

This is supplied as a 33% wetted material, meaning the compound is wetted with approximately 33% water. Dry 2,4-dinitrophenylhydrazine is explosive (H206, EUH001), and the water desensitizes it to reduce this hazard and improve handling safety.

Can Molekula supply this product in bulk quantities?

Yes, we can accommodate bulk orders for 2,4-Dinitrophenylhydrazine (33% wetted material) upon request, subject to availability and regulatory compliance.

What documentation comes with an order of this product?

Each order includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS/SDS), and a product specification sheet detailing purity, storage, and handling instructions.
