Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 219.31 g/mol gives 4-Amino Levamisole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Amino Levamisole (CAS 76497-82-0), a certified reference material (molecular formula C11H13N3S, MW 219.31 g/mol) for analytical method development and quality control.
4-Amino Levamisole (C11H13N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
