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 4,4'-((6-Chloroquinoxaline-2,3-diyl)bis(oxy))dianiline.
4,4'-((6-Chloroquinoxaline-2,3-diyl)bis(oxy))dianiline (CAS 64360-02-7), molecular formula C20H15ClN4O2 and molecular weight 378.81 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4'-((6-Chloroquinoxaline-2,3-diyl)bis(oxy))dianiline (C20H15ClN4O2) is characterized by a steroid 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4,4'-((6-Chloroquinoxaline-2,3-diyl)bis(oxy))dianiline 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.
