Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S,3S,4S,5R,6S)-6-(5-Chloro-2-(2,4-dichlorophenoxy)phenoxy)-3,4,5-trihydroxytetrahydro-2H-pyran-2-carboxylic acid.

(2S,3S,4S,5R,6S)-6-(5-Chloro-2-(2,4-dichlorophenoxy)phenoxy)-3,4,5-trihydroxytetrahydro-2H-pyran-2-carboxylic acid (CAS 63156-12-7), molecular formula C18H15Cl3O8 and molecular weight 465.67 g/mol, is a CATO reference standard with documented purity and traceability.

(2S,3S,4S,5R,6S)-6-(5-Chloro-2-(2,4-dichlorophenoxy)phenoxy)-3,4,5-trihydroxytetrahydro-2H-pyran-2-carboxylic acid (C18H15Cl3O8) 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.

As a certified reference material (CRM), (2S,3S,4S,5R,6S)-6-(5-Chloro-2-(2,4-dichlorophenoxy)phenoxy)-3,4,5-trihydroxytetrahydro-2H-pyran-2-carboxylic acid 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.
