Description

The molecular framework of 475481-99-3 4-(Chloromethyl)-2-(2-methoxyphenyl)-5-methyl-1,3-oxazole MFCD08457264 (C12H12ClNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

475481-99-3 4-(Chloromethyl)-2-(2-methoxyphenyl)-5-methyl-1,3-oxazole MFCD08457264 (CAS 475481-99-3), molecular formula C12H12ClNO2 and molecular weight 237.68 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 475481-99-3 4-(Chloromethyl)-2-(2-methoxyphenyl)-5-methyl-1,3-oxazole MFCD08457264 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.
