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 Beclomethasone Dipropionate monograph is available and quoted.
Yes. The 17- and 21-monopropionates and free beclomethasone differ in mass and retention time, so they show up separately in the purity profile.
Beclomethasone dipropionate is also supplied as a monohydrate, which carries a small amount of water and assays slightly lower on an as-is basis. Tell us which form is on the label.
Powders, inhaler formulations, nasal sprays and creams. Creams and sprays need an extraction step, so send the labeled strength with the sample.
