Description
As a certified reference material (CRM), 7-(3-Chloropropoxy)-2-hydroxychroman-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 7-(3-Chloropropoxy)-2-hydroxychroman-4-one (CAS 261529-76-4), a certified reference material (molecular formula C12H13ClO4, MW 256.68 g/mol) for analytical method development and quality control.
7-(3-Chloropropoxy)-2-hydroxychroman-4-one (C12H13ClO4) 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.
