Chemical Structure
Description
The occurrence of 6283-74-5 D7XNF76O0K O,O-Diacetyl tartaric acid anhydride (3R-trans)-Dihydro-2,5-dioxofuran-3,4-diyl diacetate EINECS 228-502-7 UNII-D7XNF76O0K is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6283-74-5 D7XNF76O0K O,O-Diacetyl tartaric acid anhydride (3R-trans)-Dihydro-2,5-dioxofuran-3,4-diyl diacetate EINECS 228-502-7 UNII-D7XNF76O0K (CAS 6283-74-5), molecular formula C8H8O7 and molecular weight 216.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6283-74-5 D7XNF76O0K O,O-Diacetyl tartaric acid anhydride (3R-trans)-Dihydro-2,5-dioxofuran-3,4-diyl diacetate EINECS 228-502-7 UNII-D7XNF76O0K (C8H8O7) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
