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 a chromatographic assay, with detection selected for the compound. Full testing to the USP Tranexamic Acid monograph is available and quoted.
Tranexamic acid is the trans isomer. The cis isomer has the same mass, so it is separated by HPLC and reported as a named impurity.
It absorbs only at low UV wavelengths, so the lab uses a detection method suited to the compound.
Usually as a white powder, and also in serums and creams. Finished products need extraction, so tell us the matrix.
