It is widely used in qualitative and quantitative analysis to identify the presence of aldehydes and ketones through the formation of characteristic crystalline derivatives with specific melting points. It is also used in environmental and air quality testing where DNPH derivatives help detect and measure carbonyl pollutants such as acetaldehyde in air samples. Additionally it is used in educational laboratories to demonstrate derivatization reactions and confirm the presence of carbonyl functional groups.

It is formed to convert volatile and reactive acetaldehyde into a more stable solid derivative that can be easily isolated stored and characterized. This improves the accuracy and convenience of detecting and studying aldehydes in laboratory analysis.

It is an orange to reddish crystalline solid typically insoluble in water but soluble in organic solvents. This compound belongs to a class of hydrazones that are commonly used for the identification of carbonyl compounds such as aldehydes and ketones.
