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 2-(5-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)isoxazol-3-yl)-N-(isoxazol-3-yl)acetamide.
2-(5-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)isoxazol-3-yl)-N-(isoxazol-3-yl)acetamide (CAS 1209377-50-3), molecular formula C16H13N3O5 and molecular weight 327.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(5-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)isoxazol-3-yl)-N-(isoxazol-3-yl)acetamide (C16H13N3O5) is characterized by a flavonoid 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.
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 2-(5-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)isoxazol-3-yl)-N-(isoxazol-3-yl)acetamide 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.
