3-Acetyl-2,6,6-trimethyl-4,5,6,7-tetrahydro-1-benzofuran-4-one CAS 937604-46-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Acetyl-2,6,6-trimethyl-4,5,6,7-tetrahydro-1-benzofuran-4-one.

3-Acetyl-2,6,6-trimethyl-4,5,6,7-tetrahydro-1-benzofuran-4-one (CAS 937604-46-1), molecular formula C13H16O3 and molecular weight 220.26 g/mol, is a CATO reference standard with documented purity and traceability.

3-Acetyl-2,6,6-trimethyl-4,5,6,7-tetrahydro-1-benzofuran-4-one (C13H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
