P-Toluenesulfonic Acid
SINOBIO
2904100000
Product Name: P-Toluene Sulfonic acid
Formula: C7H8O3S·H2O
Molecular weight: 190.2
CAS: 104-15-4,6192-52-5 (Monohydrate)
UN No. 2585
Appearance: White acicular crystal
P-toluenesulfonic acid is widely used in the synthesis of medicines, pesticides, stabilizers for polymerization reactions, and catalysts for organic synthesis (esters, etc.). Also used as an intermediate and resin curing agent for medicines and coatings.
Used as edible essence, daily chemical essence and pharmaceutical intermediates.
1. It is an important raw material for the synthesis of doxycycline, dipyridamole, amoxicillin, cefadroxil intermediates, etc. in medicine.
2. It is widely used as a catalyst for reaction in organic chemical synthesis (such as: ester products, textile auxiliaries, photographic films, electronic products, new materials, etc.).
3. It is widely used as a curing agent in resin, paint, wood-based panels, casting, paint and other industries, and the curing speed is fast, and the paint film does not change color.
4. It is widely used in chemical synthesis such as medicine and pesticide.
5. Catalytic use in electronics, new polymer materials, flavors and fragrances and daily chemical products.

1. Catalyst in organic synthesis: p-toluenesulfonic acid is a strong organic acid, often used as an organic catalyst in organic synthesis. Because of its catalytic activity and good selectivity, it is used in a variety of organic synthesis reactions.
2. Solubility and physical form: p-Toluenesulfonic acid is white needle or powder crystal, soluble in water, alcohol, ether and other polar solvents. This good solubility makes its catalysis in solution more convenient and efficient.
3. Stability: p-Toluenesulfonic acid shows good stability during storage and use and can maintain its catalytic activity for a long time. However, it is incompatible with strong oxidising agents, strong bases and most common metals, so contact with these substances needs to be avoided during storage and use.
4. Other applications: In addition to its use as a catalyst for organic synthesis, p-toluenesulfonic acid has applications in other fields, but the specific details and scope may vary depending on different application scenarios.
