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 Betahistine Hydrochloride monograph is available and quoted.
The two hydrochloride groups make up about a third of the weight, so a free base result is much lower than a salt result. Tell us whether the label states the dihydrochloride, the free base or another salt such as the mesilate.
Yes, it picks up moisture readily, so keep samples sealed. Absorbed water lowers the as-is assay.
