Benzimidazole anthelmintic and fungicide
Identity: Thiabendazole
IUPAC name: 4-(1H-benzimidazol-2-yl)-1,3-thiazole
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 and UV spectroscopy, a color reaction and thin-layer chromatography, assay by nonaqueous titration, related compounds by thin-layer chromatography, residue on ignition, melting range, and loss on drying. Full testing to the USP Thiabendazole monograph is available and quoted.
Chromatographic purity and mg per unit by the method matched to the compound, identity against a reference standard. 1 unit.

Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
No. The $250 test covers identity, purity and quantity by HPLC-UV for purity and quantity and LC-MS for identity. Full testing to the USP Thiabendazole monograph is available and quoted.
A titration measures total basic content and does not separate thiabendazole from related compounds. HPLC gives a purity profile and a specific assay against a reference standard, and LC-MS confirms the mass.
Thiabendazole is also used as a postharvest fungicide, so it comes up in residue work. The $250 test is for raw material or product purity and content; trace residue analysis in foods is a separate method and is quoted.
Thiabendazole is fairly stable as a dry solid but can break down in solution under UV light. Any degradation shows up as extra peaks in the HPLC purity profile.
