Chemical Structure
Description
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.
1-(Pyridin-2-ylmethyl)-3-(thiophen-2-ylmethyl)-1-(thiophen-3-ylmethyl)urea (CAS 1235119-31-9), molecular formula C17H17N3OS2 and molecular weight 343.47 g/mol, is a CATO reference standard with documented purity and traceability.
1-(Pyridin-2-ylmethyl)-3-(thiophen-2-ylmethyl)-1-(thiophen-3-ylmethyl)urea (C17H17N3OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.
