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.

δ6-Testosterone
CAS:Producto controladoDelta6-Testosterone is a natural steroid hormone that belongs to the group of steroid drugs. It is a potent androgen, or male sex hormone, which stimulates the development and maintenance of male sexual characteristics, including the growth of prostate gland and seminal vesicles. The effects of Delta6-testosterone are mediated by binding to and activating the Androgen Receptor (AR). The effects may also be increased when Delta6-testosterone binds to AR in combination with other hormones such as estradiol. Delta6-Testosterone is metabolized by the liver into testosterone through the cytochrome p450 enzyme system. This process begins with conversion of Delta6-testosterone into 6alpha-dihydrotestosterone (DHT) by 5a-reductase. DHT can then be converted into testosterone by 3beta-hydroxysteroid dehydrogenase/3alpha-hydroxysteroid dehydrogenase (3betaHSD) or 17beta hydFórmula:C19H26O2Pureza:Min. 95%Peso molecular:286.41 g/mol6-Bromo-1,2,3,4-tetrahydronaphthalen-2-ylamine hydrochloride

CAS:2-Acetylnaphthalene is a solid compound that can be produced by the asymmetric synthesis of methyl ketones. It has been shown to have photochemical properties, and absorbs ultraviolet light in the range of 240-280 nm. 2-Acetylnaphthalene also has strong uv absorption and intramolecular hydrogen bonding, which gives it a high binding constant for acylation reactions. This compound may exist as two different forms: a metastable form with an open ring structure and a stable form with a closed ring structure. The two forms are interconvertible by hydrogen bonding or rotation about the double bond in the molecule. 2-Acetylnaphthalene is used as a photoinitiator in wastewater treatment and as an intermediate in the production of diethyl succinate.Fórmula:C12H10OPureza:Min. 95%Peso molecular:170.21 g/mol7b-Hydroxy cholesterol 3b-acetate
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/molIlexsaponin A1
CAS:Ilexsaponin A1 is a natural saponin compound, which is derived from the plant Ilex pubescens.

CAS:<p>Cholesterol 2,4-Dichlorobenzoate (CDCB) is a crystalline solid that forms the polymorphs of monoclinic, orthorhombic, and hexagonal. This compound has been traditionally used as a food additive in many commercial products to improve flavor and stability. The membranes of bacteria are composed of cholesterol 2,4-dichlorobenzoate. The nature of the compound is such that it can exist as two different conformers: the trans conformer with the chloro group on one side and the benzoate on the other or the cis conformer with both chloro groups on one side. The monoclinic form has two conformational isomers: propionate and acetate. These isomers are not distinguishable by X-ray diffraction but can be distinguished by infrared spectroscopy.</p>Pureza:Min. 95%Peso molecular:559.65 g/molDL-Aspartic acid dimethyl ester hydrochloride
