Chemical Structure

3,3''-Dioctyl-2,2':5',2''-terthiophene CAS 155166-89-5 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 3,3''-Dioctyl-2,2':5',2''-terthiophene.

CATO supplies 3,3''-Dioctyl-2,2':5',2''-terthiophene (CAS 155166-89-5), a certified reference material (molecular formula C28H40S3, MW 472.81 g/mol) for analytical method development and quality control.

3,3''-Dioctyl-2,2':5',2''-terthiophene (C28H40S3) contains sulfur-containing functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
