Serotonin antagonist and reuptake inhibitor (SARI)
Identity: Trazodone hydrochloride
IUPAC name: 2-[3-[4-(3-chlorophenyl)piperazin-1-yl]propyl]-[1,2,4]triazolo[4,3-a]pyridin-3-one;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 HPLC retention time, assay by HPLC, organic impurities by HPLC, two trace impurities by LC-MS/MS, plus residue on ignition and loss on drying. Full testing to the USP Trazodone Hydrochloride 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 assay and LC-MS for identity. Full testing to the USP Trazodone Hydrochloride monograph is available and quoted.
Two possible process impurities are alkylating compounds that must be controlled at trace levels, below what HPLC-UV can see. That LC-MS/MS limit test is outside the $250 test and is quoted separately.
Powder and tablets. Tablets are ground and extracted, and the result is reported as trazodone hydrochloride or as percent of label claim.
