How Vanguard tests Atropine sulfate

Method for the $250 identity, purity and quantity test: Chromatographic assay, with detection selected for the compound, against a reference standard, with results in 3 to 5 business days.

The USP Atropine monograph covers identity by infrared spectroscopy and a gold chloride precipitation test, assay by nonaqueous titration with perchloric acid, foreign alkaloids by thin-layer chromatography, residue on ignition, readily carbonizable substances, optical rotation, melting range, and water content. Full testing to the USP Atropine or Atropine Sulfate 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

Tests and prices

$250

Questions about Atropine sulfate testing

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

No. The $250 test covers identity, purity and quantity by a chromatographic assay, with detection selected for the compound. Full testing to the USP Atropine or Atropine Sulfate monograph is available and quoted.

Is atropine a single enantiomer?

No. Atropine is the racemate of hyoscyamine. A standard HPLC test reports total atropine, and telling the enantiomers apart needs a chiral method or optical rotation.

What are the common degradation products of atropine?

Atropine hydrolyzes to tropine and tropic acid and can dehydrate to apoatropine. These separate by HPLC and differ in mass.

Which form of atropine is tested?

Samples are usually atropine sulfate, as powder or solution. The free base is about 83 percent of the sulfate monohydrate weight, and the report states which basis is used.
