For professionals in the pharmaceutical sector, identifying reliable sources for critical intermediates is paramount. Pyridine-3-sulfonyl Chloride (CAS: 16133-25-8) stands out as a vital component, particularly in the synthesis of Vonoprazan Fumarate. Understanding its properties, applications, and the best practices for procurement from manufacturers is key to ensuring a smooth and efficient production process.

Pyridine-3-sulfonyl Chloride is characterized by its appearance as a colorless to yellow liquid, with a high purity often exceeding 99.0%. Its chemical formula is C5H4ClNO2S, and it plays an indispensable role as an intermediate in the creation of Vonoprazan Fumarate, a potent potassium-competitive acid blocker used in treating conditions related to gastric acid secretion. This makes sourcing high-quality Pyridine-3-sulfonyl Chloride a strategic imperative for pharmaceutical companies.

When looking to buy Pyridine-3-sulfonyl Chloride, several factors come into play. Firstly, purity is critical. Manufacturers typically specify purity levels like ≥99.0%, which is essential for preventing unwanted side reactions and ensuring the efficacy of the final Active Pharmaceutical Ingredient (API). Secondly, reliable supply is non-negotiable. Working with a reputable Pyridine-3-sulfonyl Chloride manufacturer in China can provide the stability and volume required for commercial production. Understanding the price of Pyridine-3-sulfonyl Chloride involves considering purity, quantity, and supplier reputation.

The application of Pyridine-3-sulfonyl Chloride extends beyond just Vonoprazan Fumarate; it's a valuable sulfonylating agent in broader organic synthesis. However, its handling requires care due to its moisture-sensitive nature, often necessitating storage under inert conditions. This is a crucial point to confirm with your CAS 16133-25-8 supplier.
