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 Ethyl 2,3-dimethyl-5-(methylimino)-2,5-dihydroisoxazole-4-carboxylate.
Ethyl 2,3-dimethyl-5-(methylimino)-2,5-dihydroisoxazole-4-carboxylate (CAS 87529-27-9), molecular formula C9H14N2O3 and molecular weight 198.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2,3-dimethyl-5-(methylimino)-2,5-dihydroisoxazole-4-carboxylate (C9H14N2O3) 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. 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 Ethyl 2,3-dimethyl-5-(methylimino)-2,5-dihydroisoxazole-4-carboxylate 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.
