Description
As a certified reference material (CRM), Spironolactone Gammalactone Impurity meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Spironolactone Gammalactone Impurity (CAS 20802-57-7), a certified reference material (molecular formula C12H12ClN7O, MW 305.72 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H12ClN7O, Spironolactone Gammalactone Impurity contains a nitrogen-containing heterocyclic scaffold, 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 305.72 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.
