Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ethyl 4-oxo-3H,4H-pyrrolo[2,1-f][1,2,4]triazine-6-carboxylate.
CATO supplies ethyl 4-oxo-3H,4H-pyrrolo[2,1-f][1,2,4]triazine-6-carboxylate (CAS 869067-01-6), a certified reference material (molecular formula C9H15N3O3, MW 213.23 g/mol) for analytical method development and quality control.
ethyl 4-oxo-3H,4H-pyrrolo[2,1-f][1,2,4]triazine-6-carboxylate (C9H15N3O3) 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.
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.
