Chemical Structure
Description
The molecular framework of 2-(1-Thiophen-2-yl-ethyl)-2H-pyrazol-3-ylamine (C9H11N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-(1-Thiophen-2-yl-ethyl)-2H-pyrazol-3-ylamine (CAS 956949-76-1) is a high-purity analytical reference standard with the molecular formula C9H11N3S and a molecular weight of 193.27 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-(1-Thiophen-2-yl-ethyl)-2H-pyrazol-3-ylamine 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.
