Description
As a certified reference material (CRM), 1-(4-Nitrophenyl)piperidin-4-one O-(4-chlorobenzyl) oxime 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 1-(4-Nitrophenyl)piperidin-4-one O-(4-chlorobenzyl) oxime (CAS 338757-93-0), a certified reference material (molecular formula C18H18ClN3O3, MW 359.81 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(4-Nitrophenyl)piperidin-4-one O-(4-chlorobenzyl) oxime is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.81 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.
