Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(1-Ethylpiperidin-4-yl)-1,2,4,5-tetrahydropyrrolo[2,3-c]pyrazole (CAS 641991-57-3), molecular formula C12H20N4 and molecular weight 220.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(1-Ethylpiperidin-4-yl)-1,2,4,5-tetrahydropyrrolo[2,3-c]pyrazole (C12H20N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
CATO manufactures 3-(1-Ethylpiperidin-4-yl)-1,2,4,5-tetrahydropyrrolo[2,3-c]pyrazole 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.
