CAS 518-47-8: Fluoresceína sódica
Descripción:
Fluoresceína sódica, con el número CAS 518-47-8, es un compuesto orgánico sintético que pertenece a la clase de colorantes fluoresceínicos. Se caracteriza por su brillante fluorescencia verde, lo que lo hace útil en diversas aplicaciones, incluyendo la imagenología biológica, como trazador en hidrología y en el campo de la microscopía. El compuesto es soluble en agua y exhibe una fluorescencia dependiente del pH, con su intensidad de emisión variando según la acidez o alcalinidad de la solución. Fluoresceína sódica tiene una fórmula molecular de C20H10Na2O5 y un peso molecular de aproximadamente 396.3 g/mol. A menudo se utiliza en diagnósticos médicos, particularmente en oftalmología para la angiografía con fluoresceína, donde ayuda a visualizar el flujo sanguíneo en la retina. Además, se utiliza en estudios ambientales para rastrear el movimiento y la contaminación del agua. Aunque generalmente se considera seguro, la exposición a altas concentraciones puede causar irritación, y se deben tomar las medidas de seguridad adecuadas al manipular la sustancia.

Fluorescein disodium salt
CAS:Fluorescein disodium salt is used as fluorescent tracer, has been utilized in studies as a drug model, as a penetrating dye . Water soluble fluorescent dye used in permeability and vascular perfusion studies due to its small molecular radius.1 Sodium fluorescein is used as a fluorescent tracer to study blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) permeability in rodent models. The dye was used as a probe substrate in the study of organic anion transporting polypeptide (OATP) mediated drug transport in hepatocytes.5 Sodium fluorescein was also used to monitor in situ solute transportation into bone through fluorescence recovery after photobleaching (FRAP). Additional reported uses include microscopy, as a gain medium in dye laser use and to detect latent blood stains in vitro. Common derivatives of Fluorescein include fluorescein isothiocyanate (FITC), eosin and Rose Bengal (sc-296278) and Rose Bengal sodium salt This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

CAS:Fluorescein sodium salt is a fluorescent dye that is used in medical imaging. It can be used as a tracer to measure the transit time of blood through the kidneys or to identify coronary artery blockages. Fluorescein sodium salt is also used as an ingredient in some asthma inhalers, where it helps to relax the airways. This compound has been shown to reduce ocular discomfort in diabetic patients. It has been shown to be useful for the detection of fluorescence by use of a detector with a fluorescence detector and for fluorescence angiography. It is also used for vitro assays and for hydroxylation studies on fatty acids and other organic compounds. Fluorescein sodium salt can be found in many different plants, including those from the families Fabaceae, Malvaceae, and Euphorbiaceae. The plant family Fabaceae includes beans, peas, soybeans, peanuts, and lentils. The plant family Malvaceae includes okraFórmula:C20H10O5·2NaPureza:(Hplc) 90 To 102%Peso molecular:376.27 g/molRef: 3D-FF176063

CAS:Fluorescein sodium is a fluorescent dye that is used in a wide variety of applications, including fluorescence angiography, histology, and immunohistochemistry. Fluorescein sodium binds to the receptor binding sites of proteins and cells, which then emit light when excited by a laser. It is also used in asthma therapy to assess lung function and for process optimization in industries where fluorescence detectors are used. This substance has been shown to be effective for the treatment of proliferative diabetic retinopathy in both diabetic patients and animals. Fluorescein sodium can cause allergic reactions and chemical reactions if it comes into contact with skin or mucous membranes.Fórmula:C20H10O5·2NaPureza:Min. 95%Forma y color:Red PowderPeso molecular:376.28 g/molUranine
