For researchers engaged in enzyme kinetics studies or biochemical assays, the selection of high-quality reagents is paramount. When it comes to quantifying N-acetyl-β-D-glucosaminidase (NAGase) activity, 4-Nitrophenyl-N-acetyl-beta-D-glucosaminide (CAS 3459-18-5) is a go-to chromogenic substrate. However, making an informed purchase decision requires careful consideration of several key factors to ensure the reliability and accuracy of your experimental results.

Firstly, purity is critical. High-purity 4-Nitrophenyl-N-acetyl-beta-D-glucosaminide minimizes the risk of interference from impurities, ensuring that the measured color change is solely due to the enzymatic reaction. Always look for products with a guaranteed purity level, often indicated by HPLC or NMR data. The CAS number, 3459-18-5, is also a crucial identifier; verifying this number ensures you are receiving the correct chemical compound. When you aim to buy this essential chemical, checking for these specifications is vital.

Secondly, the reputation and reliability of the supplier are important. Sourcing from established biochemical suppliers like NINGBO INNO PHARMCHEM CO.,LTD. provides confidence in product quality and consistency. A reputable supplier will also offer comprehensive documentation, such as Material Safety Data Sheets (MSDS) and Certificates of Analysis (CoA), which detail the product's specifications, handling, and storage instructions. These documents are invaluable for laboratory safety and experimental validation. By paying attention to these details when you buy 4-Nitrophenyl-N-acetyl-beta-D-glucosaminide, you can enhance the precision of your NAG enzyme activity measurement and the overall success of your research endeavors.
