2-Chloro-1,4-benzenediamine sulfate (1:1)(CAS: 61702-44-1)

2-Chloro-1,4-benzenediamine sulfate (1:1) is a white crystalline solid with a molecular weight of approximately 252.84 g/mol. It has a low solubility in water (0.22 g/100 mL at 20°C) and is reactive towards acids. It shows basic properties due to the amine groups and can react with acids to form salts.

2-Chloro-1,4-benzenediamine sulfate (1:1) is typically synthesized by the reaction of 2-chloro-1,4-benzenediamine with sulfuric acid. The reaction involves the protonation of the amine groups, followed by the formation of the sulfate salt. The yield is generally high, and the reaction is conducted under mild conditions to avoid degradation of the product.

2-Chloro-1,4-benzenediamine sulfate (1:1) is primarily used in the pharmaceutical industry for the synthesis of various medicinal compounds. It is also utilized in the production of some dyes and as a component in some analytical reagents. Its use in semiconductor manufacturing and as a precursor for the development of sensors is also reported.

When handling 2-Chloro-1,4-benzenediamine sulfate (1:1), appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. It should be stored in a cool, dry place away from direct sunlight. Proper ventilation is essential, and the use of a fume hood is recommended during handling. In case of a spill, it should be cleaned up immediately using appropriate spill kits and the material safety data sheet (SDS) should be consulted for specific guidelines.
