Acetic acid, 2-hydroxy-, compd. with 2-(1-methyl-2-propen-1-ylidene)hydrazinecarboximidamide , polymer with ethenylbenzene (CAS 58496-67-6), molecular formula C5H10N4C8H8C2H4O3 and molecular weight 306.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Acetic acid, 2-hydroxy-, compd. with 2-(1-methyl-2-propen-1-ylidene)hydrazinecarboximidamide , polymer with ethenylbenzene (C5H10N4C8H8C2H4O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
