Dopamine (Hydrochloride), 10 g

A catecholamine neurotransmitter supplied as the hydrochloride salt in a 10 g research-grade powder format from STEMCELL Technologies. This off-white to white crystalline compound (molecular weight 189.64 g/mol, formula C8H11NO2·HCl) is widely used in neuroscience research to study dopaminergic signaling, receptor pharmacology, and Parkinson's disease models. It serves as a key supplement in defined cell culture media for differentiating pluripotent stem cells into midbrain dopaminergic neurons, and is routinely applied in neurochemical assays, microdialysis calibration, and behavioral neuroscience workflows.

The salt form enhances aqueous solubility for direct addition to buffers and culture media at typical working concentrations in the micromolar range. Store the dry powder tightly sealed, protected from light and humidity; refrigeration is recommended to minimize oxidation of the catechol moiety. Each bottle delivers a single-use resealable quantity suitable for repeated stock solution preparation across multiple experiments.
