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.
1263365-75-8 2-Chloro-3-(2-ethylphenyl)-1-propene MFCD18433425 (CAS 1263365-75-8), molecular formula C11H13Cl and molecular weight 180.67 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H13Cl, 1263365-75-8 2-Chloro-3-(2-ethylphenyl)-1-propene MFCD18433425 contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 180.67 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.
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.
