Clenbuterol is a synthetic small molecule belonging to the group of phenylethanolamines, chemically a chlorinated aminophenylethanolamine with a tert-butylamine group. In scientific research, it is studied as a model compound for receptor activation and signal transduction, and as a reference standard in analytical work. This compound is offered as 40 mcg tablets, exclusively for laboratory and research purposes.<\/p>\n
Clenbuterol (1-(4-amino-3,5-dichlorophenyl)-2-(tert-butylamino)ethanol) possesses the classic ethanolamine side chain characteristic of adrenergic receptor ligands, but the aromatic ring does not have two hydroxyl groups as in natural catecholamines; instead, the ring carries an amino group between two chlorine atoms. It is precisely this substitution that is structurally decisive: without the catechol motif, the compound is no longer a substrate for catechol O-methyltransferase, making it significantly more stable than the endogenous ligands in model systems. For structure-activity research, clenbuterol is therefore an instructive example of how a targeted ring substitution alters the metabolic stability of a ligand class. Furthermore, the two chlorine atoms yield a characteristic isotope pattern in mass spectrometry.<\/p>\n
In research models, clenbuterol behaves as a selective agonist of \u03b22<\/sub>-adrenergic receptor. Activation of this G-protein-coupled receptor leads to a measurable increase in cAMP in cell culture systems, and upon prolonged exposure to receptor desensitization and internalization. These two read terminals make the compound useful for monitoring receptor behavior over time in vitro. Consequently, Clenbuterol is used as a model compound and reference substance in scientific research.<\/p>\n In a laboratory context, Clenbuterol occurs in the following research areas, among others:<\/p>\n Chacune de ces applications implique des recherches contr\u00f4l\u00e9es en laboratoire ou sur des mod\u00e8les pr\u00e9cliniques.<\/p>\n Clenbuterol falls under the category of oral investigational compounds in solid tablet form within our product range. While clenbuterol activates a G-protein-coupled receptor and serves as a model for long-term receptor occupancy, other components within the same product line have been specifically chosen to cover enzymatic transformations, transport proteins, or nuclear receptors. These compounds share the oral tablet form but differ fundamentally in molecular class and investigated mechanism.<\/p>\n Clenbuterol is supplied as solid tablets containing a standardized amount of 40 mcg of active substance per tablet, packaged in units of 100. The tablets can be weighed directly in a laboratory setup or placed in a suitable medium for further analysis. Given this low unit amount of active substance, an analytical balance with sufficient resolution is the starting point.<\/p>\n Store the tablets dry at room temperature, protected from direct light and moisture, in the original packaging. Handle the compound with the usual laboratory precautions: work in a clean environment, use suitable personal protective equipment, and prevent cross-contamination with other research materials. This is of particular importance for a compound that is detected at very low concentrations in residue analysis. Keep the packaging out of reach of unauthorized persons.<\/p>\n For this compound, the content is expressed as the amount of active substance per tablet (40 mcg per tablet) instead of as a purity percentage, as is customary for tablet formulations.<\/p>\nDomaines de recherche<\/h2>\n
