Chemical Structure

4-(Chloromethyl)-2-(3-chlorophenyl)-5-methyloxazole CAS 475481-97-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Chloromethyl)-2-(3-chlorophenyl)-5-methyloxazole.

4-(Chloromethyl)-2-(3-chlorophenyl)-5-methyloxazole (CAS 475481-97-1), molecular formula C11H9Cl2NO and molecular weight 242.10 g/mol, is a CATO reference standard with documented purity and traceability.

4-(Chloromethyl)-2-(3-chlorophenyl)-5-methyloxazole (C11H9Cl2NO) contains a nitrogen-containing heterocyclic scaffold, 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; 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.

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.

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.
