Ésteres y derivados
Los ésteres son compuestos orgánicos formados por la reacción de un ácido (generalmente un ácido carboxílico) con un alcohol, liberando agua en el proceso. Su estructura química incluye un grupo funcional -COO-, donde un átomo de carbono está unido a un grupo oxígeno y un grupo alquilo o arilo. Los ésteres tienen una amplia variedad de aplicaciones en la industria, como solventes, fragancias, sabores y productos farmacéuticos. En el ámbito farmacológico, algunos ésteres se utilizan como prófarmacéuticos, ya que su estructura permite una liberación controlada o una mayor biodisponibilidad de los principios activos.
En CymitQuimica ofrecemos ésteres y sus derivados para investigación en química orgánica, formulación de fármacos y aplicaciones industriales.

CAS:Producto controlado<p>1,4-Bis(2,3,4-trimethoxybenzyl)piperazine (1,4BTMP) is a piperazine derivative that has been shown to have inotropic properties. 1,4BTMP appears to increase the force of contraction of the heart muscle by increasing intracellular calcium levels. This drug may also be useful in the treatment of ventricular fibrillation and other arrhythmias. It has been shown that 1,4BTMP protects against lipid peroxidation induced by hydrogen chloride and hydrochloric acid in isolated rat hearts. In addition, this compound has been shown to inhibit creatine kinase activity and reduce lipid peroxide formation.</p>Fórmula:C24H34O6Pureza:Min. 95%Peso molecular:418.52 g/molGuaifenesin EP Impurity B
CAS:<p>Guaifenesin (GP) is a phenylpropanoid that is used as an expectorant and cough suppressant. Guaifenesin EP Impurity B is a by-product of the synthesis of guaifenesin, which can be removed by preparative chromatography. It has been shown to catalyze reactions with acidic substrates and has the ability to form magnesium complexes. The reaction mechanism for guaifenesin EP Impurity B is not well understood, but it has been shown that hydrotalcite and magnesium oxide can remove GP from solution. This impurity also reacts with zirconium to form zirconium oxide, which can be removed by techniques such as mesoporous silica gel chromatography.</p>Fórmula:C10H14O4Pureza:Min. 95%Peso molecular:198.22 g/mol4-[(2,3,4-Trimethoxyphenyl)methyl]-1-piperazinecarboxylic acid ethyl ester
