Chemical Structure
Description
(E)-3-(dimethylamino)-1-(4-nitro-3-((phenylsulfonyl)methyl)phenyl)prop-2-en-1-one (CAS 339276-52-7), molecular formula C18H18N2O5S and molecular weight 374.41 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (E)-3-(dimethylamino)-1-(4-nitro-3-((phenylsulfonyl)methyl)phenyl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.41 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (E)-3-(dimethylamino)-1-(4-nitro-3-((phenylsulfonyl)methyl)phenyl)prop-2-en-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
