2-Iodo-1,4-benzenediamine(CAS: 69951-01-5)

2-Iodo-1,4-benzenediamine (CAS: 69951-01-5) is a crystalline solid with a molecular weight of approximately 236.04 g/mol. It has a low solubility in water (0.1 g/L) and is more soluble in organic solvents like ethanol. This compound exhibits moderate reactivity, particularly towards nucleophilic substitution reactions. It is stable under normal conditions but should be stored in a desiccator to prevent moisture absorption.

2-Iodo-1,4-benzenediamine is typically synthesized via the diazonium coupling reaction of 4-iodobenzene diazonium chloride with phenylenediamine. The synthesis involves the use of sodium nitrite and hydrochloric acid as reagents, and the yield is generally high, around 75-85%. The reaction is conducted in a well-ventilated hood to manage the toxic gases produced.

2-Iodo-1,4-benzenediamine (CAS: 69951-01-5) is primarily used in the pharmaceutical industry as an intermediate for the synthesis of various drugs. It is also utilized in the polymer industry for the modification of polymers and in the semiconductor industry for the production of electronic materials. Additionally, it has applications in the development of sensors and as a reagent in analytical chemistry.

Proper handling of 2-Iodo-1,4-benzenediamine (CAS: 69951-01-5) requires personal protective equipment (PPE) such as gloves, goggles, and a lab coat. The compound should be handled in a well-ventilated area or fume hood to prevent inhalation of toxic gases. Spills should be cleaned up immediately using appropriate absorbents, and the area should be flushed with water. Safety data sheets (SDS) should be consulted for detailed emergency response procedures and storage recommendations. Handling should be conducted with care to avoid skin contact and inhalation of dust or fumes.
