For procurement specialists and R&D scientists in the chemical and pharmaceutical industries, sourcing critical reagents like 4-Nitrophenyl-N-acetyl-β-D-glucosaminide (CAS 3459-18-5) requires careful consideration of several factors. This compound, vital as a chromogenic substrate for N-acetyl-β-D-glucosaminidase, demands high purity and consistent quality to ensure reliable assay performance. This guide aims to assist buyers in navigating the procurement process, highlighting key aspects to look for when purchasing this specialized biochemical.

Firstly, understanding the product's core function is essential. 4-Nitrophenyl-N-acetyl-β-D-glucosaminide is primarily used to detect and quantify the activity of N-acetyl-β-D-glucosaminidase. When the enzyme acts upon this substrate, it releases 4-nitrophenol, which is yellow in alkaline solutions. This colorimetric property allows for easy quantification through spectrophotometry. Key applications include diagnostic testing for various medical conditions and fundamental research into enzyme kinetics and biological pathways.

When you decide to buy, pay close attention to the specifications. The CAS number, 3459-18-5, is the unique identifier. Look for suppliers who clearly state the purity level, typically expressed as a percentage (e.g., ≥97% or ≥99%). The physical appearance, often described as an off-white crystalline powder, and solubility characteristics (e.g., soluble in water) are also important indicators of quality. Certificates of Analysis (COA) from the manufacturer are indispensable for verifying these details.

The pricing of 4-Nitrophenyl-N-acetyl-β-D-glucosaminide can vary based on purity, quantity, and the supplier's location. For bulk purchases, requesting a quote directly from manufacturers, such as NINGBO INNO PHARMCHEM, is recommended to secure the best price. Suppliers in China are often competitive due to efficient manufacturing processes and established supply chains. Evaluating multiple suppliers based on a combination of price, quality, and reliability is a prudent strategy for any buyer.
