Introduction
Sodium 6-(p-toluidine)-2-naphthalene sulfonate, referred to as MTANa, its chemical name is 6-(dimethylamino)naphthalene-2-sulfonic acid sodium salt.
Quality:
MTANa is a white crystalline powder that is soluble in water and the solution is weakly alkaline. It is an electrophile that acts as a hydrogen donor and catalyst in organic synthesis.
Use:
MTANa is widely used in organic synthesis reactions. It can be used as an absorber for hydrogen ions and is used to catalyze hydrogenation reactions, peroxidation reactions, and dye reduction reactions. It can also be used in esterification, acylation, alkylation, and condensation reactions in organic synthesis. MTANa can also be used as a dye, fluorescent, and biomarker.
Method:
MTANa is usually prepared by reacting p-toluidine with 2-naphthalene sulfonic acid to generate hydrochloride of MTANa, which is then converted to MTANa with base.
Safety Information:
MTANa is a relatively stable compound. Care should be taken to avoid contact with oxidants and strong acids during use and storage to prevent dangerous reactions. Wear appropriate protective equipment during use and avoid direct contact with skin and eyes. If the compound is ingested or touched, seek medical attention promptly and provide information and safety data sheets to your doctor.
