Methyl 5-(2-chlorophenyl)furan-2-carboxylate CAS 41019-38-9

Description

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.

Methyl 5-(2-chlorophenyl)furan-2-carboxylate (CAS 41019-38-9), molecular formula C12H9ClO3 and molecular weight 236.65 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 5-(2-chlorophenyl)furan-2-carboxylate (C12H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
