    Unlock Precision in Enzyme Research with 4-Nitrophenyl Acetate

    Product Name: 4-Nitrophenyl Acetate (4-NPA, CAS 830-03-5)
    Your Reliable Chromogenic Substrate for Hydrolytic Enzyme Assays

    Searching for a sensitive and well-characterized tool to study esterase or lipase activity? Look no further. Our high-purity 4-Nitrophenyl Acetate is the gold-standard substrate for continuous, quantitative enzymatic assays.

    Why Choose Our 4-Nitrophenyl Acetate?

    • Proven Performance: Serves as an excellent model substrate for a variety of hydrolytic enzymes, including carboxylesterases (CES1), acetylcholinesterase, lipases, and carbonic anhydrase. The enzymatic hydrolysis releases 4-nitrophenol, allowing real-time, direct spectrophotometric measurement at 405-410 nm.

    • Research-Grade Quality: Manufactured under strict quality control to ensure high purity (>98%) and consistency, providing reliable and reproducible results for your critical experiments.

    • Versatile Applications: Essential for enzyme kinetics studies, inhibitor screening, enzymatic characterization, and high-throughput assay development in biochemistry, pharmacology, and medicinal chemistry research.

    Key Applications:

    • Drug Metabolism Research: Investigate the activity and inhibition of human carboxylesterases, key enzymes involved in prodrug metabolism.

    • Toxicology & Environmental Science: Assess esterase activity in biological samples or as a biomarker.

    • Basic Enzyme Biochemistry: Determine kinetic parameters (Km, Vmax) and study catalytic mechanisms.
