20331-29-7 6867AD C13H18ClNO N-(4-sec-Butylphenyl)-3-chloropropanamide CAS 20331-29-7

Description

20331-29-7 6867AD C13H18ClNO N-(4-sec-Butylphenyl)-3-chloropropanamide (CAS 20331-29-7) is a high-purity analytical reference standard with the molecular formula C13H18ClNO and a molecular weight of 239.74 g/mol.

20331-29-7 6867AD C13H18ClNO N-(4-sec-Butylphenyl)-3-chloropropanamide (C13H18ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.

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.
