Description
CATO supplies 1,3-Dichloro-9,9-dimethyl-7-(((2S,3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)acridin-2(9H)-one (CAS 503178-95-8), a certified reference material (molecular formula C21H21Cl2NO7, MW 470.30 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1,3-Dichloro-9,9-dimethyl-7-(((2S,3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)acridin-2(9H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 470.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 1,3-Dichloro-9,9-dimethyl-7-(((2S,3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)acridin-2(9H)-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.
