Chemical Structure

2,2'-([1,1'-Binaphthalene]-2,2'-diylbis(oxy))bis(ethan-1-ol) CAS 55441-95-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-([1,1'-Binaphthalene]-2,2'-diylbis(oxy))bis(ethan-1-ol).

CATO supplies 2,2'-([1,1'-Binaphthalene]-2,2'-diylbis(oxy))bis(ethan-1-ol) (CAS 55441-95-7), a certified reference material (molecular formula C24H22O4, MW 374.43 g/mol) for analytical method development and quality control.

2,2'-([1,1'-Binaphthalene]-2,2'-diylbis(oxy))bis(ethan-1-ol) (C24H22O4) contains a flavonoid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2,2'-([1,1'-Binaphthalene]-2,2'-diylbis(oxy))bis(ethan-1-ol) 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.
