(2,4-Dichlorophenyl)hydrazine(CAS: 13123-92-7)

(2,4-Dichlorophenyl)hydazine is a white or off-white crystalline solid with a molecular weight of approximately 217.01 g/mol. It is slightly soluble in water and more soluble in organic solvents like methanol and ethanol. Chemically, it is reactive towards reducing agents and can undergo substitution reactions. This compound has a pKa of around 4.5 and is susceptible to hydrolysis under basic conditions.

(2,4-Dichlorophenyl)hydazine is commonly synthesized by the reduction of 2,4-dichlorophenylhydrazine hydrochloride with a suitable reducing agent such as sodium borohydride or lithium aluminum hydride. The reaction typically proceeds with high yield and good selectivity, though appropriate precautions must be taken due to the potential for explosive decomposition under certain conditions.

(2,4-Dichlorophenyl)hydazine finds applications in the pharmaceutical industry as an intermediate in the synthesis of drugs. It is also used in the polymer industry as a crosslinking agent and in the electronic industry for making sensors and in the semiconductor industry for various chemical processes. Its use in these industries highlights its importance in chemical manufacturing.

When handling (2,4-Dichlorophenyl)hydazine, it is crucial to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated fume hood to minimize inhalation risks. Spills should be handled with caution and cleaned up using appropriate absorbent materials. Always consult the Safety Data Sheet (SDS) for detailed information on handling and emergency procedures.
