2,7-Naphthalenedisulfonic acid, 3-amino-, sodium salt (1:2)

Description:

2,7-Naphthalenedisulfonic acid, 3-amino-, sodium salt (1:2), commonly referred to as a sodium salt of an amino-substituted naphthalenedisulfonic acid, is a chemical compound characterized by its sulfonic acid groups and an amino group attached to a naphthalene ring system. This compound typically appears as a solid, often in a crystalline form, and is soluble in water due to the presence of the sulfonate groups, which enhance its ionic character. It is primarily used in dye manufacturing, particularly for producing azo dyes, and as a pH indicator in various chemical applications. The presence of both sulfonic acid and amino functional groups contributes to its reactivity and ability to form complexes with metal ions. Additionally, it may exhibit properties such as UV absorption, making it useful in analytical chemistry. Safety data sheets should be consulted for handling and toxicity information, as with all chemical substances, to ensure proper safety measures are taken during use.
