Description
(3aR,4R,5R,6aS)-Hexahydro-4-[(3R)-5-phenyl-3-[(tetrahydro-2H-pyran-2-yl)oxy]pentyl]-5-[(tetrahydro-2H-pyran-2-yl)oxy]-2H-cyclopenta[b]furan-2-ol (CAS 856453-29-7) is a high-purity analytical reference standard with the molecular formula C28H42O6 and a molecular weight of 474.63 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, (3aR,4R,5R,6aS)-Hexahydro-4-[(3R)-5-phenyl-3-[(tetrahydro-2H-pyran-2-yl)oxy]pentyl]-5-[(tetrahydro-2H-pyran-2-yl)oxy]-2H-cyclopenta[b]furan-2-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 474.63 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).
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), (3aR,4R,5R,6aS)-Hexahydro-4-[(3R)-5-phenyl-3-[(tetrahydro-2H-pyran-2-yl)oxy]pentyl]-5-[(tetrahydro-2H-pyran-2-yl)oxy]-2H-cyclopenta[b]furan-2-ol 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.
