Chemical Structure
Description
5-(1-(2-(2,4-Dichlorophenoxy)ethyl)-1H-pyrazol-3-yl)-2-phenylthiazole (C20H15Cl2N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-(1-(2-(2,4-Dichlorophenoxy)ethyl)-1H-pyrazol-3-yl)-2-phenylthiazole (CAS 318255-95-7) is a high-purity analytical reference standard with the molecular formula C20H15Cl2N3OS and a molecular weight of 416.32 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.
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.
