Chemical Structure
Description
As a certified reference material (CRM), (1S)-2,2′-Bis(methoxymethoxy)[1,1′-binaphthalene]-3,3′-dicarboxaldehyde 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.
(1S)-2,2′-Bis(methoxymethoxy)[1,1′-binaphthalene]-3,3′-dicarboxaldehyde (CAS 176437-91-5), molecular formula C26H22O6 and molecular weight 430.45 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, (1S)-2,2′-Bis(methoxymethoxy)[1,1′-binaphthalene]-3,3′-dicarboxaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 430.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
