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 1-(2-chloroethyl)-4-methylpiperazine.
1-(2-chloroethyl)-4-methylpiperazine (CAS 39123-20-1), molecular formula C7H15ClN2 and molecular weight 162.66 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-chloroethyl)-4-methylpiperazine (C7H15ClN2) 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), 1-(2-chloroethyl)-4-methylpiperazine 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.
