1. Acts Toluenesulfonamide as a high-efficiency plasticizer and resin modifier in coating & adhesive production, improving hardness, adhesion and solvent resistance of melamine and epoxy resin formulations.

2. Serves Toluenesulfonamide CAS 1333-07-9 as a key intermediate in pharmaceutical synthesis, supporting the preparation of sulfonamide antibiotics and anti-inflammatory drug raw materials stably.

3. Functions as a brightener and additive in plastic processing, enhancing surface gloss and mechanical strength of ABS, PS and engineering plastic products effectively.

Store Toluenesulfonamide (mixture of p/o-isomers, CAS 1333-07-9, white crystalline powder, faint aromatic odor, non-flammable, mp 105-130℃) at 10–25℃ in sealed HDPE/amber glass containers in a cool, dry, well-ventilated area. Isolate from strong oxidants, strong acids & alkalis to avoid decomposition and agglomeration. Wear nitrile gloves, safety goggles and dust mask; avoid dust inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use; dispose of waste per local sulfonamide & plasticizer chemical environmental regulations.

Toluenesulfonamide is an industrial plasticizer, synthetic intermediate and polymer additive, not for direct pure-form human contact or ingestion; long-term dust exposure may irritate the respiratory tract, and accidental intake will cause gastrointestinal discomfort. In regulated applications, Toluenesulfonamide CAS 1333-07-9 features excellent plasticizing and compatibilizing performance, has high thermal stability and low volatility, and exhibits good reactivity for pharmaceutical and fine chemical synthesis with high yield.
