For researchers and formulators in the chemical and pharmaceutical industries, sourcing high-purity biochemicals like 4-Nitrophenyl Beta-D-Xylopyranoside (CAS 2001-96-9) is paramount. This glycosyl compound serves as a critical substrate in enzyme assays, particularly for determining beta-xylosidase activity, and as an intermediate in organic synthesis. Understanding how to effectively buy this product involves identifying reputable manufacturers and suppliers who can guarantee quality, consistency, and competitive pricing.

When seeking a 4-nitrophenyl beta-d-xylopyranoside supplier in China, several factors should be considered. Firstly, product purity is non-negotiable. The material's intended use, often in sensitive biochemical reactions, demands a high level of purity, typically 97% or above, as specified by analytical methods like HPLC. A reliable manufacturer will readily provide certificates of analysis detailing purity, appearance (off-white to pale yellow solid), and solubility characteristics, such as its solubility in methanol.

Secondly, the CAS number, 2001-96-9, is a crucial identifier. Ensuring your supplier correctly lists and provides material matching this CAS number is vital for avoiding errors in procurement and research. Reputable suppliers will also offer detailed specifications including molecular formula (C11H13NO7) and molecular weight (271.23). Storage recommendations, such as maintaining the product at -20°C in an inert atmosphere, also indicate a supplier's commitment to product integrity.

For businesses looking to buy 4-nitrophenyl beta-d-xylopyranoside, engaging with manufacturers directly can often yield the best results in terms of price and tailored support. Many Chinese chemical manufacturers specialize in producing a wide range of organic intermediates and biochemicals. They often have robust quality control systems and can offer bulk discounts. When inquiring about 4-nitrophenyl beta-d-xylopyranoside price, it's beneficial to request quotes for different quantities to understand the cost-effectiveness for your specific needs.

Furthermore, a good supplier will have established logistical capabilities to ensure timely and safe delivery. Whether your requirement is for laboratory-scale research or larger production batches, understanding the supplier's lead times and shipping options is important. Partnering with a manufacturer that prioritizes customer service and technical support can significantly streamline the procurement process.

In summary, when you need to purchase CAS 2001-96-9, prioritize suppliers who demonstrate transparency in product specifications, offer high purity, provide comprehensive documentation, and exhibit strong customer service. By focusing on these key aspects, you can secure a reliable source for 4-Nitrophenyl Beta-D-Xylopyranoside, ensuring the success of your critical research and development projects.
