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

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.

Which specifications should be agreed for Dopamine Hydrochloride?

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.

What packaging and storage conditions should be specified?

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.

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

Dopamine hydrochloride (CAS 62-31-7; C8H12ClNO2; 189.64 g/mol) is typically a white to off-white crystalline powder and is freely soluble in water. The Japanese Pharmacopoeia (17th edition) reports a melting point of about 248 °C with decomposition. Confirm the test method, solvent-specific solubility and acceptance limits for the quoted grade using its COA/TDS/SDS.
