Chemical Structure
Description
As a certified reference material (CRM), (Z)-{[2-(2H-1,3-benzodioxol-5-yl)cyclopropyl](4-methoxyphenyl)methylidene}amino 2,4-dichlorobenzoate 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.
(Z)-{[2-(2H-1,3-benzodioxol-5-yl)cyclopropyl](4-methoxyphenyl)methylidene}amino 2,4-dichlorobenzoate (CAS 338749-23-8), molecular formula C25H19Cl2NO5 and molecular weight 484.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (Z)-{[2-(2H-1,3-benzodioxol-5-yl)cyclopropyl](4-methoxyphenyl)methylidene}amino 2,4-dichlorobenzoate (C25H19Cl2NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
