For R&D scientists and procurement managers in the pharmaceutical and fine chemical sectors, securing a consistent supply of high-purity intermediates is paramount. One such critical compound is 3-Thiopheneboronic Acid (CAS: 6165-69-1), a versatile building block widely used in complex organic synthesis. This article serves as a guide for buyers looking to purchase this essential chemical, focusing on sourcing strategies, quality considerations, and the benefits of partnering with reputable Chinese manufacturers.

Understanding 3-Thiopheneboronic Acid

3-Thiopheneboronic Acid, with the molecular formula C4H5BO2S and a molecular weight of approximately 127.96 g/mol, typically presents as a white to light yellow crystalline powder. Its melting point, ranging from 164-169°C, is a key indicator of its purity. This compound is highly valued for its role in cross-coupling reactions, particularly the Suzuki coupling, enabling the formation of carbon-carbon bonds essential for constructing sophisticated molecular structures. Its applications span the synthesis of porphyrins, which act as telomerase inhibitors, and as a precursor for potential antibacterial agents like 1,4-disubstituted imidazoles.

Key Considerations When Buying 3-Thiopheneboronic Acid

When you need to buy 3-Thiopheneboronic Acid, several factors are crucial:

1. Purity: For pharmaceutical applications, high purity is non-negotiable. Impurities can significantly affect reaction yields and the efficacy of the final product. Always inquire about the purity levels and the analytical methods used for verification (e.g., HPLC, NMR).

2. CAS Number Verification: Ensure the CAS number 6165-69-1 is correctly listed. This unique identifier guarantees you are sourcing the exact compound required for your specific synthesis pathways.

3. Supplier Reputation: Partnering with established suppliers and manufacturers is key. Look for companies with a proven track record in producing and supplying fine chemicals and pharmaceutical intermediates. A reliable supplier in China can offer significant advantages in terms of quality control and cost-effectiveness.

4. Pricing: While cost is always a factor, it should not be the sole determinant. Competitive pricing from a reputable source ensures you receive value without compromising on quality. Understanding the market price for 3-thiopheneboronic acid will help you negotiate effectively.

5. Availability and Lead Times: For ongoing projects or production, consistent availability and predictable lead times are essential. Discuss your volume requirements and delivery schedules with your chosen manufacturer.
