Estándares farmacéuticos
Los estándares farmacéuticos son un conjunto integral de materiales de referencia esenciales para garantizar la seguridad, eficacia y calidad de los productos farmacéuticos. Esta categoría incluye estándares para ingredientes farmacéuticos activos (APIs), que son los componentes centrales responsables de los efectos terapéuticos. Además, abarca compuestos y metabolitos relevantes tanto para las industrias farmacéutica como veterinaria, proporcionando puntos de referencia para la medición y análisis precisos de estas sustancias. Los estándares de control de nitrosaminas son cruciales para detectar y mitigar las nitrosaminas potencialmente dañinas en las formulaciones de medicamentos. Los estándares de toxicología ayudan a evaluar la seguridad y los posibles efectos adversos de los compuestos farmacéuticos. Además, los estándares de activadores e inhibidores enzimáticos son vitales para la investigación y el desarrollo, permitiendo estudios precisos de las vías bioquímicas y los mecanismos de acción de los medicamentos. Estos estándares farmacéuticos son herramientas indispensables para el cumplimiento normativo, el control de calidad y la investigación, asegurando que los productos farmacéuticos cumplan con estrictos criterios de seguridad y eficacia.

1-Nitronaphthalene
CAS:<p>1-Nitronaphthalene is a nitrobenzene derivative that has been used as an intermediate in the synthesis of pharmaceuticals, dyes, and other organic compounds. 1-Nitronaphthalene is classified as a hazardous substance due to its carcinogenicity and toxicity. In particular, it can cause irritation and burns on skin contact and may be fatal if swallowed. The toxicity profile of 1-nitronaphthalene has been studied in rats, mice, guinea pigs, rabbits, hamsters, and dogs.

CAS:Mexiletine is a drug that belongs to the class of drugs called antiarrhythmics. It is used for the treatment of ventricular arrhythmias and for removing cardiac conduction abnormalities. Mexiletine acts by inhibiting the release of calcium ions from the sarcoplasmic reticulum, which leads to a reduction in excitability of the heart muscle. Mexiletine has been shown to have a matrix effect on bacterial DNA, which may be due to its ability to bind with dinucleotide phosphate or its inhibitory effects on hypersensitivity syndrome. Mexiletine also has an effect on cardiac tissue, leading to decreased contractility and increased relaxation time. The mechanism by which mexiletine leads to these effects is not well understood but may be related to its ability to interact with ion channels in myocardial cells or alter protein function in these cells. Mexiletine has been shown to have some drug interactions, such as with other drugs that are metabolized through cyFórmula:C11H17NOPureza:Min. 95%Forma y color:Yellow Clear LiquidPeso molecular:179.26 g/mol5'-Amino-5'-deoxy-2',3'-O-(1-methylethylidene)-adenosine

CAS:<p>Profenofos is a water-soluble organophosphate that can be used as a pesticide. It has been shown to have synergic effects with other pesticides, such as malathion and carbaryl. Profenofos has been studied for its toxicological properties in vitro and in vivo. These studies have shown that the lowest dose at which there are adverse effects on biochemical properties is 0.1 mg/kg of body weight. The mode of action of profenofos includes inhibition of esterases, glutathione reductase, and cytochrome P450 enzymes. This enzyme inhibition leads to an accumulation of acetylcholine in the synaptic cleft, which causes muscle paralysis and death from respiratory failure. Profenofos also affects cardiac function by blocking potassium channels, leading to heart rate changes and arrhythmias. Profenofos can be identified using chromatographic analysis or electrochemical impedance spectroscopy (EIS).

CAS:Producto controlado7b-Hydroxy cholesterol 3b-acetate is an allylic compound that is catalyzed by molybdenum, which eliminates the acetyl group at position 7 to form a double bond with the 3-position. The reaction temperature of 7b-hydroxy cholesterol 3b-acetate can be increased to high temperatures (i.e., >100°C) for the elimination process, and allylic acetates are obtained as products. The reaction starts with the addition of hexacarbonyl, which leads to a diene intermediate. This is then eliminated by adding acetamide in presence of high concentration of acetic acid and catalytic amounts of molybdenum. The low yield and efficiency, however, are major drawbacks of this process.Fórmula:C29H48O3Pureza:Min. 95%Peso molecular:444.69 g/mol2-Methyl-5-nitropyridin-3-amine
