Sodium P-Toluenesulfonate 78% (CAS 657-84-1) Specifications

Physical & Chemical Properties

Technical Advantages

• Superior solubility vs. para-toluenesulfonic acid
• Stable pH buffer capacity in formulation chemistry
• Low corrosion characteristics in metal processing

Industrial Applications

1. Pharmaceutical Intermediates

Critical for synthesizing sulfonamide antibiotics and NSAID active ingredients. Enables precise pH control in reaction media.

2. Dye & Pigment Manufacturing

Enhances chromophore solubility in textile dyes. Reduces precipitation in liquid formulations by 40% compared to standard surfactants.

3. Electroplating Solutions

Maintains bath conductivity while preventing anode passivation. Recommended concentration: 2-5% in nickel plating baths.
