Chemical Structure
Description
3-(2,6-Dichlorophenyl)-N-[2-(1H-indol-3-yl)ethyl]-5-methyl-1,2-oxazole-4-carboxamide (CAS 1020252-50-9), molecular formula C21H17Cl2N3O2 and molecular weight 414.28 g/mol, is a CATO reference standard with documented purity and traceability.
3-(2,6-Dichlorophenyl)-N-[2-(1H-indol-3-yl)ethyl]-5-methyl-1,2-oxazole-4-carboxamide (C21H17Cl2N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-(2,6-Dichlorophenyl)-N-[2-(1H-indol-3-yl)ethyl]-5-methyl-1,2-oxazole-4-carboxamide 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.
