Description

The occurrence of rel-(4R)-4-((3aS,3'R,3a'S,6S,6'R,7a'S,8aR,9R,10aR)-11-Acetoxy-6'-hydroxy-5,6',9-trimethyl-3-methylene-2,2'-dioxo-3,3a,3a',4,6,6',7',7a',8,9,10,10a-dodecahydro-2H,2'H-spiro[6,8a-methanobenzo[4,5]cyclohepta[1,2-b]furan-7,3'-benzofuran]-5'-yl)pentyl acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

rel-(4R)-4-((3aS,3'R,3a'S,6S,6'R,7a'S,8aR,9R,10aR)-11-Acetoxy-6'-hydroxy-5,6',9-trimethyl-3-methylene-2,2'-dioxo-3,3a,3a',4,6,6',7',7a',8,9,10,10a-dodecahydro-2H,2'H-spiro[6,8a-methanobenzo[4,5]cyclohepta[1,2-b]furan-7,3'-benzofuran]-5'-yl)pentyl acetate (CAS 1078711-42-8) is a high-purity analytical reference standard with the molecular formula C34H44O9 and a molecular weight of 596.71 g/mol.

The molecular framework of rel-(4R)-4-((3aS,3'R,3a'S,6S,6'R,7a'S,8aR,9R,10aR)-11-Acetoxy-6'-hydroxy-5,6',9-trimethyl-3-methylene-2,2'-dioxo-3,3a,3a',4,6,6',7',7a',8,9,10,10a-dodecahydro-2H,2'H-spiro[6,8a-methanobenzo[4,5]cyclohepta[1,2-b]furan-7,3'-benzofuran]-5'-yl)pentyl acetate (C34H44O9) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), rel-(4R)-4-((3aS,3'R,3a'S,6S,6'R,7a'S,8aR,9R,10aR)-11-Acetoxy-6'-hydroxy-5,6',9-trimethyl-3-methylene-2,2'-dioxo-3,3a,3a',4,6,6',7',7a',8,9,10,10a-dodecahydro-2H,2'H-spiro[6,8a-methanobenzo[4,5]cyclohepta[1,2-b]furan-7,3'-benzofuran]-5'-yl)pentyl acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
