Chemical Structure
Description
(3AR,4R,6aR)-4-decyl-3-methylenedihydrofuro[3,4-b]furan-2,6(3H,6aH)-dione (CAS 154674-22-3), molecular formula C17H26O4 and molecular weight 294.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, (3AR,4R,6aR)-4-decyl-3-methylenedihydrofuro[3,4-b]furan-2,6(3H,6aH)-dione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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,6aR)-4-decyl-3-methylenedihydrofuro[3,4-b]furan-2,6(3H,6aH)-dione 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.
