CATO supplies 3-((4-Amino-2-methylpyrimidin-5-yl)methyl)-4-methyl-5-(2-(((3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)ethyl)thiazol-3-ium chloride (CAS 260370-52-3), a certified reference material (molecular formula C18H28N4O6SC2H3O2, MW 487.55 g/mol) for analytical method development and quality control.
3-((4-Amino-2-methylpyrimidin-5-yl)methyl)-4-methyl-5-(2-(((3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)ethyl)thiazol-3-ium chloride (C18H28N4O6SC2H3O2) contains a flavonoid core, an amide group, a sulfone 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.
As a certified reference material (CRM), 3-((4-Amino-2-methylpyrimidin-5-yl)methyl)-4-methyl-5-(2-(((3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)ethyl)thiazol-3-ium chloride 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.
