||Luminol, luminescent ammonia
||Almost white powder
Luminol, CAS 521-31-3, also known as luminescent ammonia. The chemical name is 3-amino-phthaloyl hydrazide. At room temperature, it is a blue crystal or pale yellow powder, which is a relatively stable synthetic organic compound. The chemical formula is C8H7N3O2. The details of Lumino provided by Desheng are shown below.
Application of Luminol in criminal investigation
Luminol is a strong acid, which has a certain stimulating effect on the eyes, skin, and respiratory tract. Because hemoglobin contains iron, which catalyzes the decomposition of hydrogen peroxide, it turns hydrogen peroxide into water and monooxygen. Monooxygen reoxidizes luminol to make it glow. Therefore, Lumino is widely used in criminal investigations. Even if the blood at the crime scene has been wiped or removed, forensics can still use Luminol to find their location. In fact, the investigator sprayed the luminol and activator solution in the area to be investigated, and the iron in the blood immediately catalyzed the luminescent reaction of luminol, causing it to produce blue light. The amount of catalyst required for this reaction is very small, so Luminol can detect traces of blood. The luminescence lasts about 30 seconds, which can be observed through long exposure photos, and the surrounding environment should not be too bright.
Lumino's application in criminal investigation
Luminol for chemiluminescence
Luminol is a chemical fluorescent molecule that can be converted into an excited amino phthalate in the presence of hydrogen peroxide molecules, which emits strong fluorescence. Hydrogen peroxide is the product of many biological oxidation reactions, so it is easy to link these biological oxidation reactions with light detection by introducing Luminol. For example, the glucose oxidase / catalase probe can detect the concentration of hydrogen peroxide or glucose in the sample, and the response time is only 0.5s (dynamic method).
It can be seen that Lumino is still widely used. In addition to criminal investigation, it can also be used for immunochemiluminescence reactions, for the detection of sex hormones, drug abuse, and cardiovascular and reproductive system diseases. Luminol produced by Desheng has high product purity and good shape, which can be widely used in the above-mentioned applications. Welcome to contact us for further consultation.
