Chemical Structure
Description
The occurrence of Methyl 3-(5-methylisoxazol-3-yl)acrylate 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 Methyl 3-(5-methylisoxazol-3-yl)acrylate (CAS 109203-36-3), a certified reference material (molecular formula C8H9NO3, MW 167.16 g/mol) for analytical method development and quality control.
Methyl 3-(5-methylisoxazol-3-yl)acrylate (C8H9NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures Methyl 3-(5-methylisoxazol-3-yl)acrylate 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.
