7-Diethylamino-4-methylcoumarin
CAS:7-Diethylamino-4-methylcoumarin is a fluorescence probe that can be used in applications such as the study of hydrogen bonding interactions. It is excited by laser light and emits a red-shifted fluorescent light. 7-Diethylamino-4-methylcoumarin is a hydroxyl group analogue of coumarin, which has been shown to have physiological effects on the liver cells. The absorption spectrum of 7-Diethylamino-4-methylcoumarin is sensitive to changes in pH and chemical stability. A decrease in pH increases the intensity of the emission while an increase in pH decreases the intensity of the emission. This compound can also be used to label nucleic acids during polymerase chain reactions (PCR) or for sample preparation before analysis using nuclear magnetic resonance spectroscopy (NMR).

Producto descatalogadoVitamin A palmitate
CAS:Vitamin A palmitate is a fat-soluble vitamin that has antioxidant properties. It is available as a supplement in the form of retinol and retinyl palmitate. Vitamin A palmitate is an inactive form of vitamin A that can be converted to retinol in vivo by esterases and other enzymes. The conversion of vitamin A palmitate to retinol may be inhibited by various substances, such as estradiol benzoate. This conversion leads to the formation of free radicals, which cause oxidative injury to cells. Studies have shown that vitamin A palmitate can be toxic for humans because it interferes with the synthesis of mucin, an important constituent of human lungs and airways. Vitamin A palmitate also alters gene expression in some experimental models, leading to changes in cell growth or death.
