Description
CATO supplies 265989-31-9 4-Methyl-3-oxo-N-[2-(phenylmethoxy)phenyl]pentanamide 4-Methyl-3-oxopentanoic acid N-(2-Benzyloxyphenyl)amide N-2-Benzyloxyphenyl Isobutyrylacetamide (CAS 265989-31-9), a certified reference material (molecular formula C19H21NO3, MW 311.37 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 265989-31-9 4-Methyl-3-oxo-N-[2-(phenylmethoxy)phenyl]pentanamide 4-Methyl-3-oxopentanoic acid N-(2-Benzyloxyphenyl)amide N-2-Benzyloxyphenyl Isobutyrylacetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.37 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
