Description
As a certified reference material (CRM), n-(Prop-2-yn-1-yl)piperazine-1-sulfonamide 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.
n-(Prop-2-yn-1-yl)piperazine-1-sulfonamide hydrochloride (CAS 1258640-72-0) is a high-purity analytical reference standard with the molecular formula C7H13N3O2SHCl and a molecular weight of 239.72 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, n-(Prop-2-yn-1-yl)piperazine-1-sulfonamide hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
