myo-Inositol Trispyrophosphate Hexasodium Salt (CAS 23103-35-7)

1. Product Overview

myo-Inositol Trispyrophosphate Hexasodium Salt (CAS 23103-35-7) has molecular formula C₆H₆Na₆O₂₁P₆ and MW 737.88 g/mol. It is a hexasodium salt of myo-inositol substituted with three cyclic pyrophosphate groups at the 1,2:3,4:5,6 positions. The compound features a cyclohexane backbone with six stereocenters and serves as a functionalized inositol derivative incorporating phosphorus–oxygen linkages. Used as a specialized organophosphorus building block in synthetic methodology and biochemical research.

2. Key Features and Benefits

• Cyclic Pyrophosphate Motif: Three pyrophosphate groups attached to the inositol ring provide multiple phosphorylation sites for derivatization.

• Hexasodium Salt Form: Enhanced water solubility compared to the free acid form; stable as a solid under inert atmosphere.

• Stereochemically Defined: All six ring positions bear defined stereochemistry (1R,2S,3S,4R,5S,6R).

• Research-Grade Purity: Supplied 95% (HPLC), suitable for synthetic and analytical applications.

3. Major Applications

• Organic Synthesis: Building block for introducing cyclic pyrophosphate functionalities into larger molecular architectures.

• Biochemical Methodology: Studied as a phosphorylated inositol derivative in model systems exploring phosphate–metal interactions.

• Analytical Reference: Used as a standard in HPLC/ICP-MS method development for organophosphorus compound quantification.

• Library Synthesis: Incorporated into compound libraries for screening phosphorylated natural-product mimics (research context only).
