Chemical Structure
Description
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.
2-[(6-Methyl-4-oxo-1,2,3,4-tetrahydrocyclopenta-[c]chromen-7-yl)oxy]propanoic acid (CAS 307548-90-9), molecular formula C16H16O5 and molecular weight 288.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2-[(6-Methyl-4-oxo-1,2,3,4-tetrahydrocyclopenta-[c]chromen-7-yl)oxy]propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
