3,5-Di-tert-butyl-4-(4-(butylthio)butyl)phenol CAS 662143-18-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,5-Di-tert-butyl-4-(4-(butylthio)butyl)phenol.

3,5-Di-tert-butyl-4-(4-(butylthio)butyl)phenol (CAS 662143-18-2), molecular formula C22H38OS and molecular weight 350.60 g/mol, is a CATO reference standard with documented purity and traceability.

3,5-Di-tert-butyl-4-(4-(butylthio)butyl)phenol (C22H38OS) contains a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.

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.
