Luminol can be oxidized by many substances to produce chemiluminescence, which is the earliest research and most widely used luminescence reagent. The chemiluminescence analysis of metal ions occupies an important position in the entire research and application of chemiluminescence analysis. Some metal ions can enhance the chemiluminescence of the luminol system; some ions can inhibit the chemiluminescence of the luminol system; and some ions can directly oxidize the luminol to produce chemiluminescence. In our drug analysis, we use the catalysis or inhibition of metal ions and compounds for direct or indirect detection. Let's take a look at how luminol "extraordinarily" in drug analysis.
Application of Luminol Luminescence System in Pharmaceutical Analysis
1. Direct or indirect detection using the catalysis or inhibition of metal ions and metal ion compounds, such as the determination of sodium nitroprusside (SNP) and catechol compounds. Certain reducing substances such as citric acid, citrate esters, Vc, ascorbic acid, etc. can also be detected by the metal ion-luminol luminescence system.
2. The enhancement or inhibition of the chemiluminescence reaction of luminol by biomolecules and organic substances. DNA, albumin, glucose, and uric acid can enhance the chemiluminescence reaction of luminol, thus establishing their own detection methods. In an alkaline medium, the inhibitory effect of ascorbic acid on the Luminol-K3Fe(CN)6 system can be used to determine ascorbic acid. Luminol-K3Fe(CN)6 series can also be used to monitor glucose and lactic acid. Thiol-containing drugs, promazine, etc. have an inhibitory effect on the luminol luminescence system, and a detection method is proposed accordingly.
3. Preparation of expendable chemiluminescence sensor. Luminol and other reagents are fixed on ion exchange resin to develop a chemiluminescence flow injection sensor, which is used for the determination of Vc. Combine enzyme immobilized column with FIA, use immobilized enzyme reactor, detect by luminol, it has been used for glucose, alcohol, oxalate, lactate, choline, uric acid in serum and urine, etc. Detection.
Seeing more of the power of luminol, we suddenly discovered that it is acceptable to us wherever it is. This also fully illustrates its value. If you want to know more about luminol's knowledge and uses, you might as well find its manufacturer-Desheng. I believe you will be worthy of asking.

Luminol, is a yellow crystal or beige powder at room temperature and is a relatively stable chemical reagent. At the same time, luminol is a strong acid, which has a certain irritating effect on eyes, skin and respiratory tract. It is one of the oldest and most commonly used reagents. It can be oxidized by peroxide under alkaline conditions and emit light at the same time. The redox reaction between luminol and peroxide requires a catalyst, which is generally more Valence metal ions, peroxidases such as iron, horseradish peroxidase, etc. This method is often used to detect the content of peroxides, heavy metals, peroxidase, and the derived free radicals, for toxicant analysis And analysis methods based on peroxidase and glucose oxidase. Under normal circumstances, the chemiluminescence reaction between luminol and hydrogen peroxide is very rapid in the presence of certain catalysts. The most commonly used catalyst is metal ions. In a large concentration range, the concentration of metal ions is directly proportional to the luminescence intensity, so that chemiluminescence analysis of certain metal ions can be performed. This reaction can be used to analyze organic compounds containing metal ions to achieve Very high sensitivity. The second is to use the inhibitory effect of organic compounds on the chemiluminescence reaction of luminol to determine the organic compounds that have a quenching effect on the chemiluminescence reaction. The third is the indirect determination of inorganic or organic compounds through coupling reactions. Luminol Luminescence Principle One is that sodium hypochlorite oxidizes luminol to make it glow; The second is that hydrogen peroxide reacts with sodium hypochlorite to generate oxygen and oxidize luminol to make it glow: The first is the equation for the reaction of sodium hypochlorite and hydrogen peroxide: NaClO+ H2O2== NaCl + O2+ H2O Secondly, when luminol reacts with hydroxide, a double negative ion (Dianion) is formed, which can be oxidized by oxygen generated by the decomposition of hydrogen peroxide, and the product is an organic peroxide. The peroxide is very unstable and immediately decomposes nitrogen (Luminol is not oxidized by organic oxidants such as dimethyl sulfoxide to generate nitrogen, but to generate nitrogen-containing organics) to generate excited 3-aminophthalic acid . In the transition from the excited state to the ground state, the released energy exists in the form of photons with a wavelength in the blue part of visible light. The method of indirect determination by coupling refers to the combination of one reaction that can produce or consume chemiluminescence reactants with another chemiluminescence reaction, so that indirect chemiluminescence determination of certain substances can be achieved. This method is used when determining the purity of certain substrate enzymes.
