Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 204.10 g/mol gives 2,5-Dichloro-N-isopropylaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,5-Dichloro-N-isopropylaniline (CAS 54962-85-5), molecular formula C9H11Cl2N and molecular weight 204.10 g/mol, is a CATO reference standard with documented purity and traceability.
2,5-Dichloro-N-isopropylaniline (C9H11Cl2N) contains a nitrogen-containing heterocyclic scaffold, 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 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.
As a certified reference material (CRM), 2,5-Dichloro-N-isopropylaniline 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.
