1,2,3,4-Tetrahydrobenzo[h]quinolin-3-ol(CAS: 5423-67-6)

1,2,3,4-Tetrahydrobenzo[h]quinolin-3-ol is a white crystalline solid with a molecular weight of approximately 225.24 g/mol. It is slightly soluble in water but highly soluble in organic solvents like ethanol and acetone. Chemically, it is less reactive compared to its parent compound, benzo[h]quinolin-3-ol, with moderate reactivity towards acidic and basic conditions. It has a melting point of about 168-170°C and a boiling point of around 280-285°C under reduced pressure.

1,2,3,4-Tetrahydrobenzo[h]quinolin-3-ol can be synthesized via the reduction of benzo[h]quinolin-3-one using a hydrogenation process in the presence of a catalyst like palladium on carbon. Typically, this involves dissolving the quinone in a suitable solvent, adding a hydrogenation catalyst, and hydrogenating under conditions of pressure and temperature until the desired reduction product is achieved, with high selectivity and good yield.

1,2,3,4-Tetrahydrobenzo[h]quinolin-3-ol is utilized in the pharmaceutical industry for its potential as a precursor in the synthesis of certain medicinal agents. It also finds application in the polymer industry for the development of novel materials, and in the field of sensors and semiconductors for its electronic properties.

When handling 1,2,3,4-Tetrahydrobenzo[h]quinolin-3-ol, it is advisable to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to avoid inhalation. Spills should be cleaned up carefully using appropriate materials, and the area should be thoroughly washed down with water. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal guidelines.
