Chemical Structure
Description
The molecular framework of 3-(hydroxymethyl)-5-methyl-1,2-oxazole-4-carboxylic acid (C6H7NO4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-(hydroxymethyl)-5-methyl-1,2-oxazole-4-carboxylic acid (CAS 1779855-86-5), molecular formula C6H7NO4 and molecular weight 157.12 g/mol, is a CATO reference standard with documented purity and traceability.
