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 Acetohydroxamic Acid monograph is available and quoted.
Hydroxylamine is a starting material and a breakdown product of acetohydroxamic acid, which can hydrolyze back to hydroxylamine and acetic acid. Its level is a useful sign of how a lot was made and stored.
It is a very small, polar molecule with weak UV absorbance, so the lab uses a detection method suited to the compound.
