Identity: Prednisolone (anhydrous)
IUPAC name: (8S,9S,10R,11S,13S,14S,17R)-11,17-dihydroxy-17-(2-hydroxyacetyl)-10,13-dimethyl-7,8,9,11,12,14,15,16-octahydro-6H-cyclopenta[a]phenanthren-3-one
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, assay by HPLC, chromatographic purity by HPLC, specific rotation, loss on drying, residue on ignition and a selenium limit. Full testing to the USP Prednisolone 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 with UV detection for purity and assay, and LC-MS for identity. Full testing to the USP Prednisolone monograph is available and quoted.
Yes. The sesquihydrate holds water of crystallization, so its assay on an as-is basis is lower than the anhydrous form. Tell us which form is on the label.
Some synthesis routes use selenium reagents to form the double bond in ring A. The limit checks that none is carried into the final material.
Yes. Suspensions are mixed, sampled by weight and dissolved before HPLC. Send the labeled concentration so the result can be compared.
