Chemical Structure
Description
(E)-1-(1H-benzo[d][1,2,3]triazol-1-yl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one (CAS 519054-07-0) is a high-purity analytical reference standard with the molecular formula C18H17N3O4 and a molecular weight of 339.35 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (E)-1-(1H-benzo[d][1,2,3]triazol-1-yl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), (E)-1-(1H-benzo[d][1,2,3]triazol-1-yl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-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.
