Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Methyl-3-(3-(thiophen-2-yl)propyl)-1h-pyrazol-5-amine (CAS 1152656-87-5), molecular formula C11H15N3S and molecular weight 221.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Methyl-3-(3-(thiophen-2-yl)propyl)-1h-pyrazol-5-amine (C11H15N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
