FAQ - Technical & Supply Chain

• Q:

  Does CAS 62-31-7 identify Dopamine Hydrochloride or Dopamine free base?

  A: Dopamine Hydrochloride, CAS 62-31-7, is the hydrochloride salt of dopamine. It is not dopamine free base; its systematic name is 4-(2-aminoethyl)benzene-1,2-diol hydrochloride. State the salt form and CAS number in the specification.
• Q:

  What should be confirmed for the intended use of Dopamine Hydrochloride?

  A: Before procurement, confirm material suitability for the intended use and applicable local regulatory requirements. The product page does not establish a therapeutic, pharmaceutical or dosage claim, so the buyer must verify the exact grade and documentation for the application.
• Q:

  Which specifications should be agreed for Dopamine Hydrochloride?

  A: Confirm salt identity, physical form, assay requirement, water or loss on drying, related substances, residual solvents and any required metal or impurity limits. The batch specification should use the same analytical methods and basis as the quotation.
• Q:

  What packaging and storage conditions should be specified?

  A: Confirm packaging compatible with the offered form and destination requirements. Check light, oxygen and moisture sensitivity, and use tightly closed, appropriately protected containers under the supplier's recommended conditions.
• Q:

  What appearance, melting range and solubility should be expected for Dopamine Hydrochloride?

  A: Dopamine hydrochloride CAS 62-31-7, formula C8H12ClNO2 and molecular weight 189.64, is normally a white to off-white crystalline powder. Reported melting points are generally above 230 C, and the salt is freely soluble in water and soluble in methanol but practically insoluble in ether and toluene, so confirm the offered form and analytical basis.
