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)-[(2,6-Dichlorophenyl)methoxy]({[3-nitro-4-(phenylsulfanyl)phenyl]methylidene})amine.
(E)-[(2,6-Dichlorophenyl)methoxy]({[3-nitro-4-(phenylsulfanyl)phenyl]methylidene})amine (CAS 477852-26-9), molecular formula C20H14Cl2N2O3S and molecular weight 433.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-[(2,6-Dichlorophenyl)methoxy]({[3-nitro-4-(phenylsulfanyl)phenyl]methylidene})amine (C20H14Cl2N2O3S) is characterized by a steroid core, an amide group, a sulfone 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (E)-[(2,6-Dichlorophenyl)methoxy]({[3-nitro-4-(phenylsulfanyl)phenyl]methylidene})amine 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.
