Compared with other compounds in its class, the molecular weight of 322.74 g/mol gives {6-Chloro-4-methyl-7-[(2-methylprop-2-en-1-yl)-oxy]-2-oxo-2H-chromen-3-yl}acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies {6-Chloro-4-methyl-7-[(2-methylprop-2-en-1-yl)-oxy]-2-oxo-2H-chromen-3-yl}acetic acid (CAS 887833-97-8), a certified reference material (molecular formula C16H15ClO5, MW 322.74 g/mol) for analytical method development and quality control.
{6-Chloro-4-methyl-7-[(2-methylprop-2-en-1-yl)-oxy]-2-oxo-2H-chromen-3-yl}acetic acid (C16H15ClO5) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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 {6-Chloro-4-methyl-7-[(2-methylprop-2-en-1-yl)-oxy]-2-oxo-2H-chromen-3-yl}acetic 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.
