Chemical Structure
Description
Owing to a steroid core, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage, fluorine substitution, o-DAN2PHOS is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 501.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
o-DAN2PHOS (CAS 1289463-93-9) is a high-purity analytical reference standard with the molecular formula C20H13F6O3PSNa and a molecular weight of 501.33 g/mol.
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.
CATO manufactures o-DAN2PHOS under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
