Chemical Structure
Description
As a certified reference material (CRM), 4,4'-(Butane-1,4-diylbis(oxy))dibenzaldehyde 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.
4,4'-(Butane-1,4-diylbis(oxy))dibenzaldehyde (CAS 77355-00-1), molecular formula C18H18O4 and molecular weight 298.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4'-(Butane-1,4-diylbis(oxy))dibenzaldehyde (C18H18O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
