Chemical Structure
Description
As a certified reference material (CRM), 4-Amino-2.6-dichlorophenol 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.
4-Amino-2.6-dichlorophenol hydrochloride (CAS 42486-53-3), molecular formula C6H5Cl2NOHCl and molecular weight 214.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Amino-2.6-dichlorophenol hydrochloride (C6H5Cl2NOHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
