Chemical Structure
Description
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 supplies 5-(Tert-butyl) 2-methyl 6,7-dihydrooxazolo[5,4-c]pyridine-2,5(4H)-dicarboxylate (CAS 259809-74-0), a certified reference material (molecular formula C13H18N2O5, MW 282.29 g/mol) for analytical method development and quality control.
5-(Tert-butyl) 2-methyl 6,7-dihydrooxazolo[5,4-c]pyridine-2,5(4H)-dicarboxylate (C13H18N2O5) contains a nitrogen-containing heterocyclic scaffold, 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).
As a certified reference material (CRM), 5-(Tert-butyl) 2-methyl 6,7-dihydrooxazolo[5,4-c]pyridine-2,5(4H)-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.
