Alpha-1 adrenergic agonist (phenethylamine)
Identity: Phenylephrine bitartrate
IUPAC name: 2,3-dihydroxybutanedioic acid;3-[(1R)-1-hydroxy-2-(methylamino)ethyl]phenol
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, HPLC retention time and a tartrate test, assay by HPLC, organic impurities by HPLC, and optical rotation, pH, loss on drying and residue on ignition. Full testing to the USP Phenylephrine Bitartrate or Phenylephrine 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, with LC-MS to confirm identity. Full testing to the USP Phenylephrine Bitartrate or Phenylephrine Hydrochloride monograph is available and quoted.
No. They are different molecules with different masses and retention times, and LC-MS identity tells them apart.
Phenylephrine is the single R enantiomer, and optical rotation checks that configuration. A standard HPLC purity test does not separate enantiomers, so chiral testing is quoted separately.
Phenylephrine is sold as the hydrochloride and the bitartrate, which differ a lot in molecular weight. Results are reported against the salt on the label.
