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 methyl 8-oxo-2,3,7,13-tetrazatricyclo[7.4.0.0²⁶]trideca-1(13),3,5,9,11-pentaene-4-carboxylate (CAS 2649318-76-1), a certified reference material (molecular formula C11H18N4O3, MW 254.29 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, methyl 8-oxo-2,3,7,13-tetrazatricyclo[7.4.0.0²⁶]trideca-1(13),3,5,9,11-pentaene-4-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
