Bis(1-methylethyl) (1S)-[1,1′-binaphthalene]-2,2′-dicarboxylate CAS 561054-81-7

Description

As a certified reference material (CRM), Bis(1-methylethyl) (1S)-[1,1′-binaphthalene]-2,2′-dicarboxylate 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.

Bis(1-methylethyl) (1S)-[1,1′-binaphthalene]-2,2′-dicarboxylate (CAS 561054-81-7) is a high-purity analytical reference standard with the molecular formula C28H26O4 and a molecular weight of 426.50 g/mol.

Bis(1-methylethyl) (1S)-[1,1′-binaphthalene]-2,2′-dicarboxylate (C28H26O4) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
