5-tert-Butyl 3-ethyl 3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-3,5-dicarboxylate CAS 926649-63-0

Description

Based on its molecular formula C13H20N2O5, 5-tert-Butyl 3-ethyl 3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-3,5-dicarboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 284.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 5-tert-Butyl 3-ethyl 3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-3,5-dicarboxylate (CAS 926649-63-0), a certified reference material (molecular formula C13H20N2O5, MW 284.31 g/mol) for analytical method development and quality control.

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.
