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 assay, with LC-MS to confirm identity. Full testing to the USP Cisapride monograph is available and quoted.
Cisapride is supplied as either form, and the monohydrate has a higher molecular weight. Water content tells the two apart, and the assay is reported on the basis you specify.
Cisapride is a racemic mixture of the cis isomer, so the optical rotation should be close to zero. A standard HPLC purity test does not separate the two enantiomers.
The trans diastereomer is a possible synthesis impurity. It differs in shape from the cis form and separates as its own peak in the HPLC purity profile.
