The occurrence of (R)-3,3’-diiodo-2,2’-bis(methoxymethoxy)-1,1’-binaphthalene is closely related to a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-3,3’-diiodo-2,2’-bis(methoxymethoxy)-1,1’-binaphthalene (CAS 189518-78-3), molecular formula C24H20I2O4 and molecular weight 626.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (R)-3,3’-diiodo-2,2’-bis(methoxymethoxy)-1,1’-binaphthalene (C24H20I2O4) contains a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 626.22 g/mol, it falls into the 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.
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.
CATO manufactures (R)-3,3’-diiodo-2,2’-bis(methoxymethoxy)-1,1’-binaphthalene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
