How long can it be stored? I found two in our lab, but one at room temperature for years and another one in 10 oC fridge.

Upon dissolving the H8502 powder, the solution turned dark purple/black. What could be the cause of this discoloration? Can the product still be considered suitable for use?
Upon dissolving the H8502 powder, the solution turned dark purple/black. What could be the cause of this discoloration? Can the product still be considered suitable for use?
1 answer-
Regarding the solubility of product H8502, it can be dissolved in alcohol at a concentration of 20 mg/mL or in water (H2O) at 100 mg/mL. It is recommended that solutions be prepared fresh and not stored for long-term use. Preparing aliquots for storage at -20°C or keeping the product in solution at 4-8°C is not advised.
Dopamine, the active component, is sensitive to light and the free base form is particularly prone to oxidation. Solutions with a pH range of 5.4 to 6.8 have been reported to remain stable for a maximum of 48 hours at 25°C, beyond which the solution may darken and become unusable.
Dopamine solutions should not be mixed with alkalis, iron salts, or oxidizing agents, and are known to be incompatible with certain antibiotics, including amphotericin, ampicillin, gentamicin sulfate, and benzylpenicillin.
In the literature, you can find some articles where the stability of this compound is indicated. For example: https://www.ncbi.nlm.nih.gov/pubmed/14651669
