C6H7O2ONO2n

C6H7O2ONO2n is a chemical formula that appears to describe a polymeric compound in which the repeating unit is C6H7O2ONO2 and n denotes the number of such units. When written as (C6H7O2ONO2)n, the notation indicates a polymer or oligomer whose molecular weight increases with n.

The ONO2 fragment is a nitrate ester group, a functional group common in energetic materials and some polymers. The C6H7O2 portion represents a hydrocarbon-derived fragment that is likely aromatic or substituted; the exact connectivity depends on the monomer from which the polymer is built. The overall structure thus combines a hydrocarbon backbone with nitrooxy functionality, giving a molecule with both carbon-rich and highly oxygenated features.

This formula is not a standard chemical name and provides limited information about stereochemistry, regiochemistry, or exact substituents. There is little publicly available data on properties, synthesis, or applications for this specific unit, and it may appear mainly in theoretical discussions or as a shorthand notation in some polymer chemistry contexts.

Safety and handling considerations align with those for nitrate esters in general, which can be energetic and sensitive to heat, shock, or friction. Appropriate safety protocols and regulatory considerations apply if a material of this type were to be synthesized or handled.

In summary, C6H7O2ONO2n denotes a hypothetical or described polymeric repeating unit featuring a nitrate ester group. Without additional structural detail or literature, it remains a descriptive notation rather than a widely characterized substance.
