2-Amino-5-methylbenzenesulfonic acid

Description:

2-Amino-5-methylbenzenesulfonic acid, also known as 5-methyl-2-aminobenzenesulfonic acid, is an organic compound characterized by the presence of an amino group (-NH2) and a sulfonic acid group (-SO3H) attached to a methyl-substituted benzene ring. This compound is typically a white to off-white crystalline solid that is soluble in water due to the sulfonic acid group, which enhances its polarity. It has applications in various fields, including as a reagent in organic synthesis and as a dye intermediate. The presence of both amino and sulfonic acid functional groups allows for diverse chemical reactivity, making it useful in the synthesis of other chemical compounds. Additionally, it is important to handle this substance with care, as it may pose health risks if ingested or inhaled, and appropriate safety measures should be taken during its use in laboratory settings. Overall, 2-amino-5-methylbenzenesulfonic acid is a significant compound in both industrial and research applications.

4-Aminotoluene-3-sulfonic acid

CAS: 88-44-8

4-Aminotoluene-3-sulfonic acid (ATSA) is a chemical compound that is used as a solvent in organic synthesis. It has been shown to inhibit the acetylation of histone H3, which may be the cause of autoimmune diseases and metabolic disorders. ATSA also blocks colony-stimulating factor (CSF), which is an effector protein that regulates the proliferation and differentiation of cells, including T cells and B cells. This compound has been used as a model system for studying the mechanism of CSF regulation and intermolecular hydrogen bonding. ATSA binds to CSF by forming hydrogen bonds with amino acid residues on the surface of CSF. Structural analysis has revealed that ATSA interacts with protein in a manner similar to other inhibitors of CSF.
