9H-Carbazol-9-ol(CAS: 54989-33-2)

9H-Carbazol-9-ol is a solid at room temperature, with a molecular weight of approximately 145.16 g/mol. It is slightly soluble in water but more soluble in organic solvents like ethanol and dichloromethane. This compound shows limited reactivity; it can undergo electrophilic substitution reactions and can be used as a precursor in the synthesis of various carbazoles and derivatives.

9H-Carbazol-9-ol is commonly synthesized from 9H-carbazole-9-carboxylic acid via reduction using sodium borohydride or lithium aluminum hydride. The reaction conditions and catalysts can vary, but the goal is to selectively reduce the carboxylic acid group to an alcohol, yielding 9H-carbazol-9-ol with good yield and selectivity.

9H-Carbazol-9-ol finds applications in the pharmaceutical industry, as a precursor for the synthesis of drug intermediates. It is also used in the polymer industry for the production of conductive polymers, and in the semiconductor industry as a component in photoresists and other materials.

When handling 9H-Carbazol-9-ol, it is essential to use proper personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a fume hood to minimize inhalation risks. Spills should be cleaned up immediately using appropriate absorbents, and the material safety data sheet (MSDS) should be consulted for detailed emergency procedures.
