Bromocresol purple sodium salt
CAS:Bromocresol purple sodium salt is a dye that emits light when it is irradiated with light of a particular wavelength. It has been used to detect amniotic fluid contamination in the laboratory and as an absorber in polymer films. Bromocresol purple sodium salt absorbs ultraviolet and visible light, which causes it to emit red light. The molecules of bromocresol purple sodium salt are long-chain triazoles, which absorb water vapor and emit infrared radiation. This property can be used to detect the presence of alkali metals. The luminescent property of bromocresol purple sodium salt can be enhanced by adding an alkali metal, such as potassium or lithium chloride, to the solution where it is dissolved.

The diazonium salt can be measured by liquid chromatography, while the hydrazone derivative can be measured by gas chromatography. This test has been used to measure the concentration of galacturonic acid in plants, pharmaceutical drugs, and reaction products.Fórmula:C7H6N4O4Pureza:Min. 95%Peso molecular:210.15 g/molFluorescein-sp-biotin
CAS:Fluorescein-sp-biotin is a biotinylated derivative of fluorescein. The conjugate is used to measure the amount of free d-biotin in samples. Fluorescein-sp-biotin binds to streptavidin, which has a high affinity for biotin, and then emits light at an excitation wavelength of 488 nm when excited with a laser. The intensity of the emitted light is proportional to the concentration of free d-biotin in the sample.

CAS:Zeta-carotene is a carotenoid pigment found in plants. It is a precursor to vitamin A and can be converted by the body into retinol, which can then be used in the eye. Zeta-carotene has been shown to inhibit the growth of cancer cells through transcriptional regulation of genes involved in lipid metabolism and cell proliferation. This carotenoid also has antioxidant properties that may help protect against cardiovascular diseases. In addition, zeta-carotene has been shown to have a positive effect on plant physiology because it is an important intermediate for photosynthesis.Fórmula:C40H60Pureza:Min. 95%Forma y color:Yellow PowderPeso molecular:540.9 g/molCodeine Impurity F
CAS:Producto controladoCodeine Impurity F is a biochemical that is an impurity of codeine. Codeine Impurity F is a byproduct of the enzymatic reaction with morphine and the bacterial strain Pseudomonas putida. Codeine Impurity F has been shown to inhibit the growth of gram-negative bacteria, including Escherichia coli and Salmonella enterica, by binding to cellular membranes and inhibiting their function. It also binds to RNA in vitro and prevents translation of mRNA from its ribosome complex. The hydroxyl group on Codeine Impurity F binds to aluminium ions, which may interfere with the absorption of other drugs such as ampicillin or tetracycline. This impurity has been shown to have an effect on biological products such as immunoglobulins and albumin.

CAS:Producto controladoRotigotine is a drug that is used to treat Parkinson's disease. It is a dopamine agonist that stimulates the release of dopamine in the brain. Rotigotine has been shown to be effective in controlling symptoms of Parkinson's disease, such as tremors and stiffness, and improving motor skills. This drug has also been shown to have a good tolerability profile, with few side effects reported. Rotigotine is rapidly absorbed from the gastrointestinal tract and metabolized by CYP2D6 into desalkyl rotigotine, which are pharmacologically inactive compounds. The mean terminal half-life for rotigotine is about 2 hours.
