Chemical Structure
Description
As a certified reference material (CRM), 2-{4-[(2H-1,3-benzodioxol-5-yl)methyl]piperazin-1-yl}quinoxaline 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.
2-{4-[(2H-1,3-benzodioxol-5-yl)methyl]piperazin-1-yl}quinoxaline (CAS 241146-76-9), molecular formula C20H20N4O2 and molecular weight 348.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-{4-[(2H-1,3-benzodioxol-5-yl)methyl]piperazin-1-yl}quinoxaline (C20H20N4O2) is characterized by a steroid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
