Description:
Propionaldehyde 2,4-dinitrophenylhydrazone, with the CAS number 725-00-8, is a chemical compound formed from the reaction of propionaldehyde and 2,4-dinitrophenylhydrazine. This compound typically appears as a yellow to orange crystalline solid, which is indicative of the presence of the dinitrophenylhydrazone functional group. It is primarily used in analytical chemistry for the qualitative and quantitative determination of aldehydes and ketones through the formation of hydrazones, which are often more stable and easier to analyze than their parent carbonyl compounds. The compound is known for its relatively low solubility in water but is soluble in organic solvents such as ethanol and acetone. Its stability and reactivity make it useful in various chemical applications, including organic synthesis and as a reagent in laboratory settings. As with many hydrazones, it may exhibit characteristic melting points and spectroscopic properties that can be utilized for identification and characterization purposes. Proper handling and safety precautions should be observed due to potential toxicity and reactivity.

CAS:<p>Propionaldehyde-2,4-dinitrophenylhydrazone (PAPDH) is a chemical compound that belongs to the class of nitro compounds. It has been shown to be a constant, exothermal reaction with an enthalpy change of ΔH = 0.9 ± 0.1 kJ/mol and a regression line with R2 = 0.99. PAPDH decomposes at temperatures above 200 °C, which is consistent with the intramolecular hydrogen bonding in the molecule and other parameters such as the nitro group and the propanal group. The kinetic data for PAPDH have been collected over the temperature range of -78 °C to 250 °C. The autocatalytic nature of this reaction can be seen from the rate constants for intramolecular hydrogen bonding and nitro groups, which are both inversely proportional to temperature.</p>Formula:C9H10N4O4Purity:Min. 95%Color and Shape:PowderMolecular weight:238.2 g/molPropionaldehyde-13C6 2,4-Dinitrophenylhydrazone
