For professionals in the chemical industry, a deep understanding of the compounds they work with is essential for optimizing synthesis, applications, and new product development. 1-Amino-5-chloroanthraquinone (CAS: 117-11-3) is a molecule that, while primarily known as a dye intermediate, possesses a rich chemical profile that makes it valuable across various sectors. As a leading manufacturer and supplier of fine chemicals, we aim to provide insight into the properties and synthesis of this important compound.

The molecular structure of 1-Amino-5-chloroanthraquinone is based on the anthraquinone skeleton, a tricyclic aromatic ketone. The presence of an amino group (-NH₂) at the 1-position and a chlorine atom (-Cl) at the 5-position significantly influences its reactivity and electronic properties. The amino group is electron-donating, while the chlorine atom is electron-withdrawing, creating a push-pull effect across the molecule. This electronic configuration contributes to its color and its utility in various chemical reactions, including substitutions and complex formations.

Common synthesis routes for 1-Amino-5-chloroanthraquinone often involve the modification of anthraquinone derivatives. One typical industrial method includes the nitration of 1-chloroanthraquinone followed by the reduction of the nitro group to an amino group. Alternatively, direct amination of suitable precursors can also yield the desired product. These processes require careful control of reaction conditions, such as temperature, pressure, and catalyst selection, to ensure high yields and purity. As a China-based chemical producer, we employ optimized synthesis protocols to deliver consistent quality.

The physical properties of 1-Amino-5-chloroanthraquinone are also noteworthy. It typically appears as a yellow powder, with a melting point in the range of 204-210°C. Its solubility is limited in water but better in polar organic solvents, a characteristic common to many polycyclic aromatic compounds. These properties are critical for formulators and chemists when designing reaction conditions or product formulations.

For businesses looking to buy 1-Amino-5-chloroanthraquinone, understanding these chemical characteristics helps in selecting the right grade and supplier. Whether you are using it for traditional dye synthesis, exploring its potential in materials science, or investigating it for pharmaceutical applications, partnering with a reliable manufacturer is key.
