(3a'R,4'S,6'R,7'R,7a'S)-4'-((R)-1,4-Dioxaspiro[4.5]decan-2-yl)tetrahydro-4'H-spiro[cyclohexane-1,2'-[1,3]dioxolo[4,5-c]pyran]-6',7'-diol CAS 871360-09-7 chemical structure

Description

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.

(3a'R,4'S,6'R,7'R,7a'S)-4'-((R)-1,4-Dioxaspiro[4.5]decan-2-yl)tetrahydro-4'H-spiro[cyclohexane-1,2'-[1,3]dioxolo[4,5-c]pyran]-6',7'-diol (CAS 871360-09-7), molecular formula C19H30O7 and molecular weight 370.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (3a'R,4'S,6'R,7'R,7a'S)-4'-((R)-1,4-Dioxaspiro[4.5]decan-2-yl)tetrahydro-4'H-spiro[cyclohexane-1,2'-[1,3]dioxolo[4,5-c]pyran]-6',7'-diol (C19H30O7) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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.
