Chemical Structure
Description
The occurrence of Inositol 1,2,5,6-tetrakis(phosphate) is closely related to a carbohydrate-derived structure, an amide group, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Inositol 1,2,5,6-tetrakis(phosphate) (CAS 91796-88-2) is a high-purity analytical reference standard with the molecular formula C6H15O18P4H4N and a molecular weight of 517.10 g/mol.
The molecular framework of Inositol 1,2,5,6-tetrakis(phosphate) (C6H15O18P4H4N) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), Inositol 1,2,5,6-tetrakis(phosphate) 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.
