2-Naphthalenol, 1-[2-(2-hydroxy-4-nitrophenyl)diazenyl]-, chromium(3+) salt (1:1)(CAS: 32517-36-5)

The compound is a crystalline solid with a molecular weight of approximately 419.1 g/mol. It is slightly soluble in water and ethanol but more soluble in organic solvents. The compound is known for its reactivity, particularly in its ability to form coordination complexes and exhibit chromophoric behavior due to its diazenyl group.

This compound is typically synthesized through the diazotization of 2-nitrophenol, followed by its condensation with 2-naphthol. The chromium(3+) salt is then formed through the coordination of the resulting diazenyl group with chromium(3+). The synthesis requires careful control of pH and temperature to achieve high yield and selectivity.

This compound finds applications in the pharmaceutical industry for its potential as a chromophore in dyes and pigments. It is also used in the development of sensors and semiconductors due to its unique optical properties. Additionally, its coordination chemistry makes it relevant in materials science and catalysis research.

Handling this compound requires the use of 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 cleaned up using appropriate absorbents and following safety protocols. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
