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 (3E)-3-{[(4-chlorophenyl)methoxy]imino}-1-{4-[(2,4-dichlorophenyl)methoxy]phenyl}propan-1-one.
CATO supplies (3E)-3-{[(4-chlorophenyl)methoxy]imino}-1-{4-[(2,4-dichlorophenyl)methoxy]phenyl}propan-1-one (CAS 477889-48-8), a certified reference material (molecular formula C23H18Cl3NO3, MW 462.75 g/mol) for analytical method development and quality control.
(3E)-3-{[(4-chlorophenyl)methoxy]imino}-1-{4-[(2,4-dichlorophenyl)methoxy]phenyl}propan-1-one (C23H18Cl3NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures (3E)-3-{[(4-chlorophenyl)methoxy]imino}-1-{4-[(2,4-dichlorophenyl)methoxy]phenyl}propan-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.
