Chemical Structure
Description
The occurrence of 1-(1-Ethylpropyl)piperazine dihydrochloride is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(1-Ethylpropyl)piperazine dihydrochloride (CAS 686721-33-5), molecular formula C9H20N2HCl and molecular weight 192.73 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(1-Ethylpropyl)piperazine dihydrochloride (C9H20N2HCl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 192.73 g/mol, it falls into the medium-molecular-weight range. 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-(1-Ethylpropyl)piperazine dihydrochloride 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.
