Chemical Structure
Description
The occurrence of 2-Tributylstannylbenzo[b]furan is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Tributylstannylbenzo[b]furan (CAS 148961-81-3) is a high-purity analytical reference standard with the molecular formula C20H32OSn and a molecular weight of 407.18 g/mol.
Structurally, 2-Tributylstannylbenzo[b]furan (C20H32OSn) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 407.18 g/mol, it falls into the moderately-high-molecular-weight range. 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.
