Chemical Structure
Description
3-(4-Chlorophenyl)-5-[(4-methoxyphenoxy)methyl]-1,2-oxazole (CAS 551921-32-5), molecular formula C17H14ClNO3 and molecular weight 315.75 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Chlorophenyl)-5-[(4-methoxyphenoxy)methyl]-1,2-oxazole (C17H14ClNO3) contains a steroid core, an amide group, 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, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-(4-Chlorophenyl)-5-[(4-methoxyphenoxy)methyl]-1,2-oxazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
