Alpha-1 adrenergic blocker
Identity: Tamsulosin hydrochloride
IUPAC name: 5-[(2R)-2-[2-(2-ethoxyphenoxy)ethylamino]propyl]-2-methoxybenzenesulfonamide;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, a chloride test and HPLC retention time, assay by HPLC, organic impurities by two HPLC procedures, enantiomeric purity by chiral HPLC, residue on ignition, and loss on drying. Full testing to the USP Tamsulosin 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 quantity and LC-MS for identity. Full testing to the USP Tamsulosin Hydrochloride monograph is available and quoted.
Tamsulosin is the R-enantiomer, and the S-enantiomer is controlled as an impurity. They have the same mass, so chiral HPLC is needed, and that test is quoted separately from the $250 test.
Yes. Tamsulosin capsules hold modified-release pellets with a small amount of drug, so the pellets are ground and fully extracted before HPLC.
