Description
Compared with other compounds in its class, the molecular weight of 344.36 g/mol gives 2-((2,2-Dimethyl-6-oxo-3,4,6,7,8,9-hexahydro-2H-cyclopenta[c]pyrano[2,3-h]chromen-10-yl)oxy)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-((2,2-Dimethyl-6-oxo-3,4,6,7,8,9-hexahydro-2H-cyclopenta[c]pyrano[2,3-h]chromen-10-yl)oxy)acetic acid (CAS 859134-29-5), molecular formula C19H20O6 and molecular weight 344.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-((2,2-Dimethyl-6-oxo-3,4,6,7,8,9-hexahydro-2H-cyclopenta[c]pyrano[2,3-h]chromen-10-yl)oxy)acetic acid (C19H20O6) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 344.36 g/mol, it falls into the moderately-high-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
