In the vast landscape of chemical compounds used in research, specific CAS (Chemical Abstracts Service) registry numbers serve as unique identifiers, ensuring clarity and precision. CAS 3459-18-5 refers to 4-Nitrophenyl-N-acetyl-beta-D-glucosaminide, a vital synthetic compound widely recognized for its role as a chromogenic substrate in biochemical assays. Understanding its chemical structure and properties is fundamental to appreciating its significance in scientific investigations.

4-Nitrophenyl-N-acetyl-beta-D-glucosaminide is specifically engineered to be a substrate for N-acetyl-β-D-glucosaminidase (NAGase). When this enzyme acts upon the molecule, it cleaves the glycosidic bond, releasing 4-nitrophenol. This release is coupled with a visible color change, typically to yellow under alkaline conditions, which can be easily measured using spectrophotometric methods. This characteristic makes it invaluable for enzyme activity measurement, enzyme kinetics studies, and diagnostic applications, such as assessing kidney health through urine analysis. The ability to reliably buy this chemical online from reputable sources like NINGBO INNO PHARMCHEM CO.,LTD. ensures consistent research outcomes.

The critical role of CAS 3459-18-5 in facilitating precise NAG enzyme activity measurement highlights the importance of specialized biochemicals in advancing scientific knowledge. Whether employed in academic research labs or clinical diagnostic settings, this compound underscores the power of tailored chemical tools in uncovering biological insights and developing new diagnostic methodologies. Its consistent performance makes it a cornerstone for many enzyme-based detection systems.
