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 quantity and LC-MS for identity. Full testing to the USP Bisoprolol Fumarate monograph is available and quoted.
Bisoprolol fumarate is a 2:1 salt, with two bisoprolol molecules per fumaric acid. This matters when results are converted between the salt and bisoprolol base.
The USP monograph measures fumaric acid by titration to confirm the salt ratio. The $250 test measures bisoprolol by HPLC, and fumarate content can be added and quoted.
Yes, bisoprolol is supplied as a racemic mixture. The standard HPLC test reports total bisoprolol; separating the enantiomers needs a chiral method, which is quoted separately.
