Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 178.06 g/mol gives 4-Chloro-2-methylaniline hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-2-methylaniline hydrochloride (CAS 3165-93-3) is a high-purity analytical reference standard with the molecular formula C7H8ClNHCl and a molecular weight of 178.06 g/mol.
4-Chloro-2-methylaniline hydrochloride (C7H8ClNHCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), 4-Chloro-2-methylaniline hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
