Chemical Structure
Description
The occurrence of 5-Hydroxy-6-methylpyridine-3,4-dicarbaldehyde 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 5-Hydroxy-6-methylpyridine-3,4-dicarbaldehyde (CAS 19099-89-9), a certified reference material (molecular formula C8H7NO3, MW 165.15 g/mol) for analytical method development and quality control.
5-Hydroxy-6-methylpyridine-3,4-dicarbaldehyde (C8H7NO3) 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 5-Hydroxy-6-methylpyridine-3,4-dicarbaldehyde 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.
