Chemical Structure
Description
CATO supplies 5-(3-Chlorophenyl)-2-methyl-1-pentene (CAS 74672-13-2), a certified reference material (molecular formula C10H10Cl2, MW 201.09 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H10Cl2, 5-(3-Chlorophenyl)-2-methyl-1-pentene contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 201.09 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.
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.
