Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Thiophen-2-yl)piperazin-2-one hydrochloride.
CATO supplies 1-(Thiophen-2-yl)piperazin-2-one hydrochloride (CAS 1284243-99-7), a certified reference material (molecular formula C8H10N2OSHCl, MW 218.70 g/mol) for analytical method development and quality control.
1-(Thiophen-2-yl)piperazin-2-one hydrochloride (C8H10N2OSHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
CATO manufactures 1-(Thiophen-2-yl)piperazin-2-one hydrochloride 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.
