5-Hydroxy-2,3,7,8-tetrahydrobenzo[g][1,3,6,9,2]tetraoxaphosphacycloundecine 5-oxide CAS 149300-81-2

Description

The molecular framework of 5-Hydroxy-2,3,7,8-tetrahydrobenzo[g][1,3,6,9,2]tetraoxaphosphacycloundecine 5-oxide (C10H13O6P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

5-Hydroxy-2,3,7,8-tetrahydrobenzo[g][1,3,6,9,2]tetraoxaphosphacycloundecine 5-oxide (CAS 149300-81-2), molecular formula C10H13O6P and molecular weight 260.18 g/mol, is a CATO reference standard with documented purity and traceability.

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.

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.
