Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N1-Cycloheptyl-N2-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)oxalamide (CAS 946298-46-0), a certified reference material (molecular formula C18H22N4O3, MW 342.39 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, N1-Cycloheptyl-N2-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)oxalamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), N1-Cycloheptyl-N2-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)oxalamide 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.
