(±)-Epinephrine-d3

(±)-Epinephrine-d3 is intended for use as an internal standard for the quantification of (±)-epinephrine (Cay-21245) by GC- or LC-MS. (±)-Epinephrine is a natural neurotransmitter that is released from the adrenal medulla and activates adrenoceptors (Kis = 15, 735, and 3,970 nM for alpha1A-, beta2-, and beta1-adrenergic receptors, respectively). Through these receptors, (±)-epinephrine may induce either contraction or relaxation of vascular smooth muscle, depending on adrenoceptor subtype expression. Formulations containing (±)-epinephrine have been used in the emergency treatment of severe allergic reactions and the induction and maintenance of mydriasis during intraocular surgery.Formal Name: 4-[1-hydroxy-2-(methyl-d3 amino)ethyl]-1,2-benzenediol.
