Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-Ethyl-5-(isopropylthio)-4H-1,2,4-triazol-3-yl)-1-((4-methoxyphenyl)sulfonyl)piperidine.
4-(4-Ethyl-5-(isopropylthio)-4H-1,2,4-triazol-3-yl)-1-((4-methoxyphenyl)sulfonyl)piperidine (CAS 672950-65-1), molecular formula C19H28N4O3S2 and molecular weight 424.58 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H28N4O3S2, 4-(4-Ethyl-5-(isopropylthio)-4H-1,2,4-triazol-3-yl)-1-((4-methoxyphenyl)sulfonyl)piperidine contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 424.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 4-(4-Ethyl-5-(isopropylthio)-4H-1,2,4-triazol-3-yl)-1-((4-methoxyphenyl)sulfonyl)piperidine 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.
