How Vanguard tests Apraclonidine 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 and a chloride test, assay by nonaqueous potentiometric titration, chromatographic purity by HPLC, and pH, loss on drying and residue on ignition. Full testing to the USP Apraclonidine 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 Apraclonidine hydrochloride testing

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

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

How is apraclonidine different from clonidine?

Apraclonidine is clonidine with an added amino group on the ring, so it is 15 mass units heavier. LC-MS and HPLC retention time tell the two apart.

Can apraclonidine eye drops be tested?

Yes. The drops are diluted and measured directly, and the result is reported as apraclonidine base or hydrochloride per mL, whichever matches the label.
