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 1-(2,4-Dimethoxyphenyl)-5-(5,5-dimethyl-1,3-dioxan-2-yl)pentan-1-one (CAS 898756-08-6), a certified reference material (molecular formula C19H28O5, MW 336.42 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, 1-(2,4-Dimethoxyphenyl)-5-(5,5-dimethyl-1,3-dioxan-2-yl)pentan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.42 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), 1-(2,4-Dimethoxyphenyl)-5-(5,5-dimethyl-1,3-dioxan-2-yl)pentan-1-one 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.
