{3-[(2,4-dichlorobenzoyloxy)methyl]-4-oxo-3,4-dihydro-2H-1-benzothiopyran-3-yl}methyl 2,4-dichlorobenzoate CAS 339028-82-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including {3-[(2,4-dichlorobenzoyloxy)methyl]-4-oxo-3,4-dihydro-2H-1-benzothiopyran-3-yl}methyl 2,4-dichlorobenzoate.

{3-[(2,4-dichlorobenzoyloxy)methyl]-4-oxo-3,4-dihydro-2H-1-benzothiopyran-3-yl}methyl 2,4-dichlorobenzoate (CAS 339028-82-9) is a high-purity analytical reference standard with the molecular formula C25H16Cl4O5S and a molecular weight of 570.27 g/mol.

The molecular framework of {3-[(2,4-dichlorobenzoyloxy)methyl]-4-oxo-3,4-dihydro-2H-1-benzothiopyran-3-yl}methyl 2,4-dichlorobenzoate (C25H16Cl4O5S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
