Description

(1S,2S)-(-)-1,2-Diaminocyclohexane-N,N'-bis(2-diphenylphosphino-1-naphthoyl) 205495-66-5 (1S,2S)-(-)-1,2-DIAMINOCYCLOHEXANE-N,N'-BIS(2-DIPHENYLPHOSPHINO-1-NAPHTHOYL);(1S,2S)-(-)-N,N'-BIS(2-DIPHENYLPHOSPHINO-1-NAPTHOYL)-1,2-DIAMINOCYCLOHEXANE;(S,S)-DACH-NAPHTHYL TROST LIGAND;ROST LIGAND (NAPHTHYL) SC11306 (CAS 205495-66-5), molecular formula C52H88N2O2P2 and molecular weight 835.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (1S,2S)-(-)-1,2-Diaminocyclohexane-N,N'-bis(2-diphenylphosphino-1-naphthoyl) 205495-66-5 (1S,2S)-(-)-1,2-DIAMINOCYCLOHEXANE-N,N'-BIS(2-DIPHENYLPHOSPHINO-1-NAPHTHOYL);(1S,2S)-(-)-N,N'-BIS(2-DIPHENYLPHOSPHINO-1-NAPTHOYL)-1,2-DIAMINOCYCLOHEXANE;(S,S)-DACH-NAPHTHYL TROST LIGAND;ROST LIGAND (NAPHTHYL) SC11306 (C52H88N2O2P2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), (1S,2S)-(-)-1,2-Diaminocyclohexane-N,N'-bis(2-diphenylphosphino-1-naphthoyl) 205495-66-5 (1S,2S)-(-)-1,2-DIAMINOCYCLOHEXANE-N,N'-BIS(2-DIPHENYLPHOSPHINO-1-NAPHTHOYL);(1S,2S)-(-)-N,N'-BIS(2-DIPHENYLPHOSPHINO-1-NAPTHOYL)-1,2-DIAMINOCYCLOHEXANE;(S,S)-DACH-NAPHTHYL TROST LIGAND;ROST LIGAND (NAPHTHYL) SC11306 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.
