Chemical Structure
Description
4-chloro-2-(2,3-dichlorophenyl)aniline (CAS 1510554-64-9), molecular formula C12H8Cl3N and molecular weight 272.56 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-chloro-2-(2,3-dichlorophenyl)aniline (C12H8Cl3N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 272.56 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
