Chemical Structure
Description
CATO supplies 4,6-Dihydro-1H,3H-furo[3,4-c]furan-1,3-dione-d4 (CAS 1643544-03-9), a certified reference material (molecular formula C7D7BrO, MW 194.08 g/mol) for analytical method development and quality control.
Structurally, 4,6-Dihydro-1H,3H-furo[3,4-c]furan-1,3-dione-d4 (C7D7BrO) contains deuterium isotope labeling, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 194.08 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
