Chemical Structure

(1S)-2,2',3,3'-tetrahydro-6,6'-dimethyl-1,1'-Spirobi[1H-indene]-7,7'-diol CAS 1621066-64-5 chemical structure

Description

(1S)-2,2',3,3'-tetrahydro-6,6'-dimethyl-1,1'-Spirobi[1H-indene]-7,7'-diol (CAS 1621066-64-5) is a high-purity analytical reference standard with the molecular formula C19H20O2 and a molecular weight of 280.36 g/mol.

Based on its molecular formula C19H20O2, (1S)-2,2',3,3'-tetrahydro-6,6'-dimethyl-1,1'-Spirobi[1H-indene]-7,7'-diol contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 280.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), (1S)-2,2',3,3'-tetrahydro-6,6'-dimethyl-1,1'-Spirobi[1H-indene]-7,7'-diol 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.
