This article delves into the key physical and chemical properties of 4-Hydroxycarbazole that users need to know.

The compound, identified by its Chemical Name: 4-Hydroxycarbazole and Synonyms: 9H-Carbazol-4-ol, has a precise molecular formula of C12H9NO and a molecular weight of 183.20600. These fundamental identifiers are essential for accurate stoichiometric calculations and reaction planning. The physical state of 4-Hydroxycarbazole is consistently described as a white powder, which is indicative of its crystalline nature. This visual characteristic is a first-level quality check for many users.

The thermal properties of 4-Hydroxycarbazole are particularly important for processing and quality control. It exhibits a melting point in the range of 169-173°C (lit.). This specific 4-hydroxycarbazole melting point is a critical parameter for confirming its identity and purity. A deviation from this range could suggest the presence of impurities or a different crystalline form. Its boiling point is recorded as 431.4°C at 760 mmHg, indicating a relatively low volatility at standard temperatures, which is beneficial for handling and storage. The flash point of 214.7°C further signifies its moderate flammability risk.

The density of 1.362 g/cm³ and a refractive index of 1.815 are also documented properties that can be used for characterization. NINGBO INNO PHARMCHEM CO.,LTD. ensures that these specifications are met consistently for the products they supply. When you choose to buy 4-hydroxycarbazole from them, you are investing in a product with reliable, documented physical characteristics.

Understanding the proper handling and storage of 4-Hydroxycarbazole is key to maintaining its quality and extending its shelf life. The product specification highlights a moisture content of ≤0.3%, an impurity level of ≤0.3%, and a loss on drying of ≤0.5%. To preserve these conditions, it is recommended that the compound be stored at -20ºC Freezer or in a cool and dry well-closed container. Keeping it away from moisture and strong light/heat is crucial to prevent degradation. These storage requirements are essential for anyone involved in the 4-hydroxycarbazole chemical synthesis process or its downstream applications. The consistent adherence to these standards by NINGBO INNO PHARMCHEM CO.,LTD. ensures that users receive a product ready for immediate and effective use, whether for established 4-hydroxycarbazole applications or novel research.
