(R)-6,6'-Diiodo-4,4'-dimethyl-2,2',3,3'-tetrahydro-1,1'-spirobi[indene]-7,7'-diol CAS 2098225-21-7 chemical structure

Description

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.

(R)-6,6'-Diiodo-4,4'-dimethyl-2,2',3,3'-tetrahydro-1,1'-spirobi[indene]-7,7'-diol (CAS 2098225-21-7), molecular formula C19H18I2O2 and molecular weight 532.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (R)-6,6'-Diiodo-4,4'-dimethyl-2,2',3,3'-tetrahydro-1,1'-spirobi[indene]-7,7'-diol (C19H18I2O2) contains a steroid core, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 532.15 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures (R)-6,6'-Diiodo-4,4'-dimethyl-2,2',3,3'-tetrahydro-1,1'-spirobi[indene]-7,7'-diol 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.
