6-Hydroxy-3-pyridazinecarboxylic acid(CAS: 37972-69-3)

6-Hydroxy-3-pyridazinecarboxylic acid (CAS: 37972-69-3) is a white crystalline solid with a molecular weight of approximately 167.14 g/mol. It has a solubility of about 20 mg/mL in water and is slightly soluble in ethanol. Chemically, it is moderately reactive, showing some acidity and can form complexes with metal ions. It is stable under normal conditions but should be stored away from strong oxidizing agents and heat.

6-Hydroxy-3-pyridazinecarboxylic acid is typically synthesized via the condensation reaction of 3-pyridazinecarboxylic acid and hydroxylamine hydrochloride. This process often requires a catalyst such as sodium hydroxide or potassium hydroxide. The yield can be up to 85%, and the product can be purified by recrystallization from water or ethanol.

6-Hydroxy-3-pyridazinecarboxylic acid (CAS: 37972-69-3) is used in the pharmaceutical industry for the synthesis of certain drugs, particularly those that require specific functional groups. It is also used in the polymer industry as a monomer or intermediate. Additionally, it finds applications in the development of sensors and semiconductors due to its unique chemical properties.

When handling 6-Hydroxy-3-pyridazinecarboxylic acid (CAS: 37972-69-3), it is important to wear appropriate personal protective equipment (PPE) such as gloves and safety goggles. It should be stored in a fume hood to minimize inhalation risks. In case of a spill, it should be cleaned up with caution, using appropriate spill kits or neutralizing agents as needed. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
