6-[(4-Methylphenyl)Amino]-2-Naphthalenesulfonic acid （CAS# 7724-15-4)

Introduction

6-p-toluene amino-2-naphthalene sulfonic acid potassium salt, also known as 6-p-toluidino-2-naphthalenesulfonic acid potassium salt (TNAP-K).

Quality:

- White crystalline powder or crystalline in appearance.

- Soluble in water and soluble under acidic conditions.

- Yellow solution in acidic conditions and dark purple solution in alkaline conditions.

Use:

- Potassium 6-p-tolueneamino-2-naphthalene sulfonate is an organic light-emitting material mainly used as a photosensitive dye in dye-sensitized solar cells (DSSCs).

- It can absorb light energy and convert it into electricity, which can be used to improve the efficiency of solar cells.

Method:

The method for the preparation of potassium salt of 6-p-toluene amino-2-naphthalene sulfonate is generally as follows:

- React p-toluidine with 2-naphthalene sulfonic acid to produce 6-p-tolueneamino-2-naphthalene sulfonic acid.

- Then, 6-p-tolueneamino-2-naphthalene sulfonic acid is reacted with potassium hydroxide to produce 6-p-tolueneamino-2-naphthalene sulfonate potassium salt.

Safety Information:

- Potassium salt of 6-p-tolueneamino-2-naphthalene sulfonate has not been extensively studied, and limited information is available on its safety.

- When in use, follow general laboratory safety protocols, such as wearing appropriate protective equipment and avoiding contact with skin and eyes.

- In case of accidental contact or inhalation, wash or consult a doctor immediately.

Before using or handling potassium 6-p-toluene-2-naphthalene sulfonate, more detailed safety information should be consulted or a professional should be consulted.
