Description

Luminol CAS NO 521-31-3 is a high-purity chemiluminescent compound widely recognized for its ability to emit a characteristic blue glow upon reaction with an oxidizing agent in the presence of a catalyst. This unique property makes it an indispensable reagent in forensic science, analytical chemistry, and biochemical research for the detection of trace metals, particularly iron and copper, and for visualizing bloodstains. It is a critical material for diagnostic kit manufacturers, forensic laboratories, and research institutions requiring reliable and sensitive detection systems.

Application

• Forensic Science: Primary reagent for the presumptive detection and visualization of latent bloodstains at crime scenes.
• Analytical Chemistry: Used as a chemiluminescent probe for the detection and quantification of trace metals (e.g., Fe, Cu, Co, Cr) and certain enzymes like horseradish peroxidase (HRP) in various matrices.
• Biochemical Research & Diagnostics: Key component in chemiluminescence immunoassays (CLIA), Western blotting, and DNA hybridization assays for high-sensitivity detection.
• Environmental Monitoring: Employed in assays to detect and measure reactive oxygen species (ROS) and antioxidant capacity in environmental samples.
• Industrial Hygiene & Safety: Utilized in test kits for monitoring peroxide-based explosives and certain oxidizing contaminants.
• Academic & Pharmaceutical R&D: Serves as a model compound for studying chemiluminescence mechanisms and developing new luminescent materials.

Quality Control

Our Luminol is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by FT-IR, to ensure it meets the stringent requirements for sensitive detection applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect performance.
