Chemical Structure

1-(Butylsulfanyl)-4-chlorobenzene CAS 16155-34-3 chemical structure

Description

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.

1-(Butylsulfanyl)-4-chlorobenzene (CAS 16155-34-3) is a high-purity analytical reference standard with the molecular formula C10H13ClS and a molecular weight of 200.73 g/mol.

The molecular framework of 1-(Butylsulfanyl)-4-chlorobenzene (C10H13ClS) is characterized by sulfur-containing functionality, chlorine substitution, an aromatic ring system. 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.

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.
