Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethylene-13C2-diamine 2HCl.
Ethylene-13C2-diamine 2HCl (CAS 77435-60-0), molecular formula [13C]2H8N2 2*HCl and molecular weight 84.55 g/mol, is a CATO reference standard with documented purity and traceability.
Ethylene-13C2-diamine 2HCl ([13C]2H8N2 2*HCl) contains 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.
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), Ethylene-13C2-diamine 2HCl 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.
