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.

N,N-Diethyl-N'-1-naphthylethylenediamine oxalate
CAS:N,N-Diethyl-N'-1-naphthylethylenediamine oxalate (NDENOX) is a naphthalene derivative that is used to inhibit the growth of bacteria. It binds to the extracellular site on the bacterial cell membrane and inhibits sulfadiazine uptake. NDENOX has been shown to be effective against S. aureus and other bacteria that are resistant to sulfonamides, but not against Staphylococcus epidermidis or E. coli. This drug also inhibits enzyme activity in damaged human serum, which may be due to its binding with kynurenine or pupal. NDENOX is hydrolyzed by hydrochloric acid and procaine to release naphthalene and diethylenetriamine, respectively.Fórmula:C18H24N2O4•C2H2O4xPureza:Min. 95 Area-%Forma y color:PowderPeso molecular:332.39 g/molIlexsaponin B1

CAS:Acriflavine is a chemical agent that inhibits the growth of bacteria by binding to nuclear DNA and disrupting the synthesis of proteins. Acriflavine has been shown to be effective in treating infections caused by wild-type strains of bacteria, but has little effect on resistant mutants. It also has little effect on bacterial cells that are not actively growing (i.e., in the stationary phase). Acriflavine binds to DNA and acts as a crosslinking agent, which prevents transcription and replication. This drug also inhibits mitochondrial functions. Acriflavine is commonly used in combination with benzalkonium chloride or other antimicrobial agents because it does not have any bactericidal effects when used alone.END>>Pureza:Min. 95%Forma y color:Orange To Red Brown SolidPeso molecular:259.73 g/mol(R)-(+)-(2,2-Bis(Diphenylphosphino)-1,1-binaphthyl)palladium(II)chloride
