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

(1R,1 inverted exclamation markaR,2S,2 inverted exclamation markaS)-2,2 inverted exclamation marka-Di-tert-butyl-2,3,2 inverted exclamation marka,3 inverted exclamation marka-tetrahydro-1H,1 inverted exclamation markaH-(1,1 inverted exclamation marka)biisophosphindolyl (1R,1 inverted exclamation markaR,2S,2 inverted exclamation markaS)-DuanPhos 528814-26-8 (CAS 528814-26-8) is a high-purity analytical reference standard with the molecular formula C24H44P2 and a molecular weight of 394.55 g/mol.

The molecular framework of (1R,1 inverted exclamation markaR,2S,2 inverted exclamation markaS)-2,2 inverted exclamation marka-Di-tert-butyl-2,3,2 inverted exclamation marka,3 inverted exclamation marka-tetrahydro-1H,1 inverted exclamation markaH-(1,1 inverted exclamation marka)biisophosphindolyl (1R,1 inverted exclamation markaR,2S,2 inverted exclamation markaS)-DuanPhos 528814-26-8 (C24H44P2) is characterized by organophosphorus functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

CATO manufactures (1R,1 inverted exclamation markaR,2S,2 inverted exclamation markaS)-2,2 inverted exclamation marka-Di-tert-butyl-2,3,2 inverted exclamation marka,3 inverted exclamation marka-tetrahydro-1H,1 inverted exclamation markaH-(1,1 inverted exclamation marka)biisophosphindolyl (1R,1 inverted exclamation markaR,2S,2 inverted exclamation markaS)-DuanPhos 528814-26-8 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.
