Angiotensin II receptor blocker (sartan)
Identity: Valsartan
IUPAC name: (2S)-3-methyl-2-[pentanoyl-[[4-[2-(2H-tetrazol-5-yl)phenyl]phenyl]methyl]amino]butanoic acid
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 HPLC retention time, assay by HPLC, organic impurities by HPLC, residue on ignition, water content, and an absorbance test. Full testing to the USP Valsartan 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 Valsartan monograph is available and quoted.
Valsartan is the S-enantiomer, and the R-enantiomer is a known impurity. They have the same mass, so a chiral HPLC method is needed to measure it, which is quoted separately.
No. Trace nitrosamines such as NDMA and NDEA, which can occur in sartans from some synthesis routes, need a dedicated LC-MS/MS or GC-MS method. That testing is quoted separately.
