  • Applications

    Octopamine Hydrochloride (CAS 770-05-8) is used primarily as an intermediate for the synthesis of amine-containing bioactive compounds in pharmaceutical and agrochemical R&D, and as a source of octopamine for library development and structure-activity studies (SAR). In neuroscience-focused research, it serves as a tool compound to probe octopaminergic signaling in invertebrates. It is also used as a reference standard for analytical methods quantifying biogenic amines (e.g., HPLC/LC-MS). Additionally, it can function as a building block for specialty polymers or coatings that require amine functionality. Its use should be considered within the constraints of local regulations and formulation limits.
