Ritalinic acid
Based on 1 Customer Validation
Ritalinic acid (Ritalinate) is a metabolite of Methylphenidate. Ritalinic acid has no biological activity or only extremely low biological activity. The concentration of Ritalinic acid detected in university campus sewage shows a gradual upward trend in the first semester, while no obvious periodic variation pattern related to academic stress is observed in the second semester. Ritalinic acid can be used in studies related to attention deficit disorder, narcolepsy, depression and attention deficit hyperactivity disorder.

H2O : 4.03 mg/mL (18.38 mM; ultrasonic and adjust pH to 12 with 1 M NaOH)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
