Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-N-{[2-(2H-1,3-benzodioxol-5-yl)cyclopropyl](4-methoxyphenyl)methylidene}hydroxylamine 338749-16-9 4N-037.
CATO supplies (E)-N-{[2-(2H-1,3-benzodioxol-5-yl)cyclopropyl](4-methoxyphenyl)methylidene}hydroxylamine 338749-16-9 4N-037 (CAS 338749-16-9), a certified reference material (molecular formula C18H17NO4, MW 311.33 g/mol) for analytical method development and quality control.
The molecular framework of (E)-N-{[2-(2H-1,3-benzodioxol-5-yl)cyclopropyl](4-methoxyphenyl)methylidene}hydroxylamine 338749-16-9 4N-037 (C18H17NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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)-N-{[2-(2H-1,3-benzodioxol-5-yl)cyclopropyl](4-methoxyphenyl)methylidene}hydroxylamine 338749-16-9 4N-037 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.
