Methyl 2-((3a'R,4'S,5a'S,8'R,9a'S,9b'S)-4'-((R)-1,2-dihydroxyethyl)octahydrospiro[cyclohexane-1,2'-[1,3]dioxolo[4,5-d]pyrano[3,2-b]pyran]-8'-yl)acetate CAS 871360-12-2

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.

Methyl 2-((3a'R,4'S,5a'S,8'R,9a'S,9b'S)-4'-((R)-1,2-dihydroxyethyl)octahydrospiro[cyclohexane-1,2'-[1,3]dioxolo[4,5-d]pyrano[3,2-b]pyran]-8'-yl)acetate (CAS 871360-12-2), molecular formula C19H30O8 and molecular weight 386.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 2-((3a'R,4'S,5a'S,8'R,9a'S,9b'S)-4'-((R)-1,2-dihydroxyethyl)octahydrospiro[cyclohexane-1,2'-[1,3]dioxolo[4,5-d]pyrano[3,2-b]pyran]-8'-yl)acetate (C19H30O8) 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 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.
