Chemical Structure
Description
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.
1-(4-chlorophenyl)ethane-1,2-diamine dihydrochloride (CAS 40658-64-8), molecular formula C8H11ClN2HCl and molecular weight 207.10 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-chlorophenyl)ethane-1,2-diamine dihydrochloride (C8H11ClN2HCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 1-(4-chlorophenyl)ethane-1,2-diamine dihydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
