Chemical Structure
Description
The occurrence of o-DANPHOS is closely related to a flavonoid core, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
o-DANPHOS (CAS 1289463-84-8) is a high-purity analytical reference standard with the molecular formula C19H14F3O6PS2Na and a molecular weight of 513.39 g/mol.
Structurally, o-DANPHOS (C19H14F3O6PS2Na) contains a flavonoid core, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 513.39 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), o-DANPHOS 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.
