Chemical Structure
Description
As a certified reference material (CRM), Phenyl 1-Thio-α-D-mannopyranoside Tetrabenzoate 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.
Phenyl 1-Thio-α-D-mannopyranoside Tetrabenzoate (CAS 65236-83-1), molecular formula C40H32O9S and molecular weight 688.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Phenyl 1-Thio-α-D-mannopyranoside Tetrabenzoate (C40H32O9S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 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.
