Chemical Structure
Description
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.
(2R,3R,4R,5R)-2-(((4-chlorobenzoyl)oxy)methyl)-5-methoxytetrahydrofuran-3,4-diyl bis(4-chlorobenzoate) (CAS 29755-00-8) is a high-purity analytical reference standard with the molecular formula C27H21Cl3O8 and a molecular weight of 579.81 g/mol.
The molecular framework of (2R,3R,4R,5R)-2-(((4-chlorobenzoyl)oxy)methyl)-5-methoxytetrahydrofuran-3,4-diyl bis(4-chlorobenzoate) (C27H21Cl3O8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
