Chemical Structure

4,4'''-Bis((2-butyloctyl)oxy)-1,1':4',1'':4'',1'''-quaterphenyl CAS 18434-08-7 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 4,4'''-Bis((2-butyloctyl)oxy)-1,1':4',1'':4'',1'''-quaterphenyl.

CATO supplies 4,4'''-Bis((2-butyloctyl)oxy)-1,1':4',1'':4'',1'''-quaterphenyl (CAS 18434-08-7), a certified reference material (molecular formula C48H66O2, MW 675.04 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4,4'''-Bis((2-butyloctyl)oxy)-1,1':4',1'':4'',1'''-quaterphenyl is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 675.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 4,4'''-Bis((2-butyloctyl)oxy)-1,1':4',1'':4'',1'''-quaterphenyl 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.
