(S,S,S)-(-)-Tol-SKP CAS 1548897-80-8 chemical structure

Description

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.

(S,S,S)-(-)-Tol-SKP (CAS 1548897-80-8) is a high-purity analytical reference standard with the molecular formula C48H46O2P2 and a molecular weight of 716.83 g/mol.

Based on its molecular formula C48H46O2P2, (S,S,S)-(-)-Tol-SKP contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 716.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
