Dopamine

About Dopamine

Dopamine is an impurity of Noradrenaline carrying the CAS registry number 51-61-6. Formula C8H11NO2, molecular weight 153.18 g/mol. Its systematic (IUPAC) name is 4-(2-aminoethyl)benzene-1,2-diol. It is also known as 3-Hydroxytyramine or Oxytyramine.

The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a characterised impurity of Noradrenaline, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory filings. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, Dopamine is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
