Compared with other compounds in its class, the molecular weight of 240.26 g/mol gives Ethyl 6-(hydroxymethyl)-5,6,7,8-tetrahydropyrazolo[5,1-b][1,3]oxazepine-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 6-(hydroxymethyl)-5,6,7,8-tetrahydropyrazolo[5,1-b][1,3]oxazepine-2-carboxylate (CAS 2413410-27-0), a certified reference material (molecular formula C11H16N2O4, MW 240.26 g/mol) for analytical method development and quality control.
Ethyl 6-(hydroxymethyl)-5,6,7,8-tetrahydropyrazolo[5,1-b][1,3]oxazepine-2-carboxylate (C11H16N2O4) 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.
