5,5-Difluoro-2,2-dimethyl-1,3-dioxane-4,6-dione CAS 1031926-89-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,5-Difluoro-2,2-dimethyl-1,3-dioxane-4,6-dione.

5,5-Difluoro-2,2-dimethyl-1,3-dioxane-4,6-dione (CAS 1031926-89-2), molecular formula C6H6F2O4 and molecular weight 180.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 5,5-Difluoro-2,2-dimethyl-1,3-dioxane-4,6-dione is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
