An internal standard for the quantification of cimaterol
Cimaterol-d7 is intended for use as an internal standard for the quantification of cimaterol by GC- or LC-MS. Cimaterol is a potent agonist of β-adrenergic receptors (pEC50 = 8.13, 8.78, and 6.62 for human β1, β2, and β3, respectively).1 Formulations containing cimaterol have been used in farmed animals (swine, fowl, etc.) to increase carcass mass and to alter muscle and fat deposition.2,3
