CATO supplies Puromycin ·xHCl (CAS 53-79-2 (free base)), a certified reference material (molecular formula C22H29N7O5·xHCl, MW 507.98 g/mol) for analytical method development and quality control.
Based on its molecular formula C22H29N7O5·xHCl, Puromycin ·xHCl contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 507.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
