5-{[4-chloro-5-methyl-2-(propan-2-yl)phenoxy]methyl}furan-2-carboxylic acid (CAS 438219-43-3) is a high-purity analytical reference standard with the molecular formula C16H17ClO4 and a molecular weight of 308.76 g/mol.
5-{[4-chloro-5-methyl-2-(propan-2-yl)phenoxy]methyl}furan-2-carboxylic acid (C16H17ClO4) contains a flavonoid core, 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. 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.
CATO manufactures 5-{[4-chloro-5-methyl-2-(propan-2-yl)phenoxy]methyl}furan-2-carboxylic acid 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.
