Chemical Structure
Description
The occurrence of 1,4-Bis(phenylthio)butane is closely related to sulfur-containing functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,4-Bis(phenylthio)butane (CAS 5330-89-2), a certified reference material (molecular formula C16H18S2, MW 274.44 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H18S2, 1,4-Bis(phenylthio)butane contains sulfur-containing functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 1,4-Bis(phenylthio)butane 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.
