2-Aminoanisole-4-sulfonic acid

Description:
2-Aminoanisole-4-sulfonic acid, also known as 4-Amino-2-methoxybenzenesulfonic acid, is an organic compound characterized by the presence of an amino group (-NH2), a methoxy group (-OCH3), and a sulfonic acid group (-SO3H) attached to a benzene ring. This compound typically appears as a white to light yellow crystalline solid and is soluble in water due to the sulfonic acid group, which enhances its polarity. It is commonly used in the synthesis of dyes, pharmaceuticals, and as an intermediate in organic reactions. The presence of both the amino and sulfonic acid functional groups allows for various chemical reactivity, including electrophilic substitution and coupling reactions. Additionally, 2-aminoanisole-4-sulfonic acid can exhibit biological activity, making it of interest in medicinal chemistry. Safety data indicates that it should be handled with care, as it may cause irritation upon contact with skin or eyes. Proper safety measures, including the use of personal protective equipment, are recommended when working with this compound.
