Diethyl 4-hydroxyisoxazole-3,5-dicarboxylate CAS 23468-99-7

Description

The occurrence of Diethyl 4-hydroxyisoxazole-3,5-dicarboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Diethyl 4-hydroxyisoxazole-3,5-dicarboxylate (CAS 23468-99-7), a certified reference material (molecular formula C9H11NO6, MW 229.19 g/mol) for analytical method development and quality control.

The molecular framework of Diethyl 4-hydroxyisoxazole-3,5-dicarboxylate (C9H11NO6) is characterized by an amino-acid-derived structure, 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. 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.

As a certified reference material (CRM), Diethyl 4-hydroxyisoxazole-3,5-dicarboxylate 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.
