Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.55 g/mol gives 3,4-Dichloro-N-propylaniline hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,4-Dichloro-N-propylaniline hydrochloride (CAS 2138568-12-2), a certified reference material (molecular formula C9H11Cl2NHCl, MW 240.55 g/mol) for analytical method development and quality control.
Structurally, 3,4-Dichloro-N-propylaniline hydrochloride (C9H11Cl2NHCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 240.55 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
