Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2,6-Dichlorobenzyl)-2-methyl-4H-pyran-4-one.
CATO supplies 3-(2,6-Dichlorobenzyl)-2-methyl-4H-pyran-4-one (CAS 339104-20-0), a certified reference material (molecular formula C13H10Cl2O2, MW 269.12 g/mol) for analytical method development and quality control.
3-(2,6-Dichlorobenzyl)-2-methyl-4H-pyran-4-one (C13H10Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 3-(2,6-Dichlorobenzyl)-2-methyl-4H-pyran-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.
