Esteroides e Derivados
Os esteroides são compostos orgânicos que possuem uma estrutura de quatro anéis fundidos, conhecida como núcleo esteroide. Esse núcleo pode estar ligado a vários grupos funcionais que modificam suas propriedades e funções biológicas. Os esteroides desempenham um papel fundamental na regulação dos processos metabólicos e hormonais. São utilizados na medicina para tratar distúrbios inflamatórios, doenças autoimunes e desequilíbrios hormonais. Além disso, alguns derivados de esteroides possuem potentes propriedades anti-inflamatórias, como os corticosteroides. Em terapias específicas, são utilizados para reduzir a inflamação e controlar a dor em diversas doenças.
Na CymitQuimica, oferecemos uma variedade de esteroides e seus derivados para pesquisa e desenvolvimento farmacêutico.

(betaR,deltaR)-2,3-Bis(4-fluorophenyl)-beta,delta-dihydroxy-5-(1-methylethyl)-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid hemicalcium salt
CAS:(betaR,deltaR)-2,3-Bis(4-fluorophenyl)-beta,delta-dihydroxy-5-(1-methylethyl)-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid hemicalcium salt is an impurity that is used in the production of a drug product. This product is metabolized to (betaR,deltaR)-2,3-bis(4-fluorophenyl)-beta,delta-dihydroxy-5-(1-methylethyl)-4-[(phenylamino)carbonyl]-1H-pyrrole 1 heptanoic acid which is used as an analytical standard for HPLC.Fórmula:C66H66CaF4N4O10Pureza:Min. 95%Peso molecular:1,193.34 g/molLoteprednol Impurity 10

CAS:Desfluoro atorvastatin is a crystalline polymorph of atorvastatin that has been shown to have improved flowrate and dissolution profile compared with the conventional form. Desfluoro atorvastatin is synthesized by adding a fluorine atom to a specific position in the molecule. The synthesis procedure includes chromatographic purification and analysis of impurities, which are then eliminated by diode laser irradiation. Impurities may also be eliminated through hydrogenation or recrystallization.Fórmula:C33H36N2O5Pureza:Min. 95%Cor e Forma:PowderPeso molecular:540.65 g/molDutasteride EP impurity E
