Product Information

• Name: Propionaldehyde-2,4-dinitrophenylhydrazone
• Brand: Biosynth
• Description: 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.
