How Vanguard tests Albendazole

Identity, purity and quantity are measured by the chromatographic method matched to the compound (HPLC-UV, LC-MS or GC-MS) against a reference standard, $250 per sample with results in 3 to 5 business days.

Full testing to the USP Albendazole monograph is available and quoted: identification by infrared absorption and thin-layer chromatography, assay by titration, and impurities by thin-layer chromatography.

What's reported

Salts, forms and compendial references

A USP monograph exists for Albendazole. Monograph testing is quoted.
Tell us the salt or form the label states, so quantity is reported on the same basis.

Questions about Albendazole testing

Can you tell albendazole from fenbendazole or mebendazole?

Yes. These benzimidazoles separate by HPLC and differ in mass, so a substituted powder shows up in the identity result.

What does the purity result include?

The main peak's share of the total peak area by HPLC-UV. Related compounds above the reporting limit show as separate peaks, and LC-MS can identify them on request.

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

No. The $250 test covers identity, purity and quantity against a reference standard. Full testing to the USP Albendazole monograph adds the monograph's own tests and is quoted.
