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 Carteolol monograph is available and quoted.
Dehydrocarteolol, an oxidized form of the quinolinone ring, is one of the related compounds named in the USP monograph. It appears as a separate peak in the HPLC purity profile.
Yes. Ophthalmic solutions can be diluted and tested directly, and the carteolol hydrochloride content is reported against the label concentration.
Yes, by default. The hydrochloride makes up about 11 percent of the salt by weight, so tell us if you need results on the free base basis.
