1-((4-Methyl-2-nitrophenyl)diazenyl)naphthalen-2-ol(CAS: 2425-85-6)

1-((4-Methyl-2-nitrophenyl)diazenyl)naphthalen-2-ol is a crystalline solid with a molecular weight of approximately 324.09 g/mol. It is slightly soluble in water and more soluble in organic solvents like methanol and acetone. The compound is relatively stable but can undergo thermal decomposition and reacts with strong oxidizing agents. It has a pKa of around 9.5, indicating basicity.

1-((4-Methyl-2-nitrophenyl)diazenyl)naphthalen-2-ol is synthesized via diazotization of 4-methyl-2-nitrophenol followed by coupling with naphthalen-2-ol. Commonly, this involves the use of sodium nitrite and hydrochloric acid as a catalyst. The reaction is carried out in an aqueous medium, and the diazotized product is then introduced to the naphthalen-2-ol under appropriate conditions to achieve high yield and selectivity.

1-((4-Methyl-2-nitrophenyl)diazenyl)naphthalen-2-ol is used in the pharmaceutical industry due to its potential as a drug intermediate. It is also employed in the polymer industry for developing functional materials, and in the chemical sensor industry for detecting specific analytes. Its properties make it suitable for applications in semiconductor manufacturing as well.

When handling 1-((4-Methyl-2-nitrophenyl)diazenyl)naphthalen-2-ol, it is crucial to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. The compound should be stored in a cool, dry place away from direct sunlight. It should be used in a well-ventilated area or a fume hood to minimize inhalation risk. Spills should be cleaned up with caution, and the Occupational Safety and Health Administration (OSHA) and Material Safety Data Sheet (MSDS) should be consulted for specific handling procedures.
