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 1,5-Bis(2,3,4,4,5,5-hexamethylhexan-2-yl)pentasulfane.
1,5-Bis(2,3,4,4,5,5-hexamethylhexan-2-yl)pentasulfane (CAS 31565-23-8), molecular formula C24H50S5 and molecular weight 498.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,5-Bis(2,3,4,4,5,5-hexamethylhexan-2-yl)pentasulfane (C24H50S5) is characterized by sulfur-containing functionality. 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.
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.
