CAS 4039-32-1: Bis(trimetilsilil)amide di litio
Descrizione:
Bis(trimetilsilil)amide di litio, con il numero CAS 4039-32-1, è un composto organolitico caratterizzato dalla sua forte basicità e nucleofilia. Presenta un catione di litio coordinato a un anione bis(trimethylsilyl)amide, che consiste in due gruppi trimethylsilyl legati a un atomo di azoto. Questo composto è tipicamente un solido bianco a giallo chiaro ed è altamente solubile in solventi non polari come esano e toluene, rendendolo utile in varie applicazioni di sintesi organica. Le sue forti proprietà basiche gli consentono di deprotonare un'ampia gamma di substrati, facilitando reazioni come la formazione di legami carbonio-carbonio. Inoltre, Bis(trimetilsilil)amide di litio è spesso impiegato come reagente nella sintesi di molecole organiche complesse e nella preparazione di intermediari contenenti litio. Tuttavia, deve essere maneggiato con cura a causa della sua reattività e del potenziale di reagire con l'umidità, il che può portare al rilascio di gas infiammabili. In generale, questo composto è uno strumento prezioso nella chimica organica sintetica e nella scienza dei materiali.

CAS:Lithium bis(trimethylsilyl)amide is an amide that has been used to treat bowel disease, hyperproliferative disease, and infectious diseases. It has antimicrobial activity because it inhibits the growth of certain bacteria by interfering with their metabolism. Lithium bis(trimethylsilyl)amide has been shown to have a reaction mechanism similar to other amides, which may be due to its ability to inhibit the enzyme fatty acid synthase and thus interfere with the synthesis of fatty acids. This drug also has potential anticancer properties because it inhibits the growth of cancer cells in vitro and in vivo.Formula:C6H18LiNSi2Purezza:Min. 95%Peso molecolare:167.33 g/molRef: 3D-FL165181

CAS:Lithium hexamethyl disilazide solution is an inhibitor drug that blocks the synthesis of pyrimidine compounds. It has been shown to be effective in congestive heart failure, hyperproliferative diseases such as pancreatitis and dyslipoproteinemia, coronary heart diseases, and HIV infection. Lithium hexamethyl disilazide solution binds to the cb2 receptor on the surface of activated T cells, which inhibits their ability to cause inflammation or autoimmune disease. This drug also has nitrogen atoms that are reactive and asymmetric, making it a good candidate for an inhibitor drug.Formula:C6H18LiNSi2Purezza:Min. 95%Peso molecolare:167.33 g/molRef: 3D-FL146829

CAS:Lithium bis(trimethylsilyl)amide - 1.4 M in THF is a chemical compound that belongs to the class of amides. It has been shown to be effective against bowel disease and hyperproliferative diseases such as cancer. Lithium bis(trimethylsilyl)amide - 1.4 M in THF has antimicrobial properties and can be used for the treatment of infectious diseases and coronary heart diseases, as well as an inhibitor drug for autoimmune diseases and potential anticancer agent. The mechanism of reaction involves the formation of a covalent bond with the nucleophilic center on an enzyme or receptor protein, which leads to inhibition or destruction of the target protein, depending on whether it is a kinase or phosphatase respectively. The biological activity is related to affinity for cell surface receptors and inhibition of their binding to ligands, which prevents signalling pathways from being activated.Formula:C6H18LiNSi2Purezza:Min. 95%Colore e forma:Clear LiquidPeso molecolare:167.33 g/molRef: 3D-FL165131
