Description
CATO supplies 2-(4,8,8-Trimethyl-2-oxo-7,8-dihydro-2h,6h-pyrano[3,2-g]chromen-3-yl)acetic acid (CAS 859134-97-7), a certified reference material (molecular formula C17H18O5, MW 302.32 g/mol) for analytical method development and quality control.
2-(4,8,8-Trimethyl-2-oxo-7,8-dihydro-2h,6h-pyrano[3,2-g]chromen-3-yl)acetic acid (C17H18O5) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 2-(4,8,8-Trimethyl-2-oxo-7,8-dihydro-2h,6h-pyrano[3,2-g]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.
