How Vanguard tests Ropinirole hydrochloride

Method for the $250 identity, purity and quantity test: HPLC-UV purity and assay, LC-MS identity, against a reference standard, with results in 3 to 5 business days.

The USP monograph covers identity by infrared spectroscopy, HPLC retention time and a chloride test, assay by HPLC, organic impurities by three HPLC procedures, a palladium limit test, and water and residue on ignition. Full testing to the USP Ropinirole Hydrochloride monograph is available and quoted.

What's reported

  • Purity, as percent of total peak area
  • Quantity, against the label claim
  • Identity, reported as match or no match against the reference standard
  • With monograph testing (quoted): the monograph’s tests against its limits

Questions about Ropinirole hydrochloride testing

Is the $250 test the same as USP monograph testing?

No. The $250 test covers identity, purity and quantity by HPLC-UV for purity and assay, with LC-MS to confirm identity. Full testing to the USP Ropinirole Hydrochloride monograph is available and quoted.

Why does the monograph include a palladium limit?

Palladium catalysts can be used in ropinirole synthesis, so the monograph limits residual palladium. Elemental palladium testing is quoted separately from the $250 test.

Is the result reported as ropinirole or ropinirole hydrochloride?

Results are reported against the labeled form. Ropinirole base makes up about 88% of the hydrochloride by weight, so the form matters when comparing numbers.
