Product Description
A white crystalline diol bearing a pair of tertiary hydroxyl groups, 2,5-Dimethyl-2,5-hexanediol holds a central place among intermediates for organic peroxides, pyrethroid-type insecticides, synthetic musks, and polymer crosslinkers. Its appeal comes from a symmetric molecule and reactive tertiary alcohol positions.
Highlights:
Crystalline white flakes that are simple to weigh out and work with.
Paired tertiary OH groups support efficient esterification and peroxide-generating reactions.
Symmetry lends itself to the design of symmetric peroxide crosslinking agents.
Insoluble to a large degree in benzene, CCl₄, and hydrocarbons, yet readily taken up by polar solvents.
Heat-induced sublimation allows easy purification without solvents.
High-purity options tailored to fine-chemical and polymer-grade demands.

Product Application
Classed as a specialty diol intermediate, this compound finds its main outlets in polymer crosslinking, agrochemical manufacturing, and fragrance production.
For polymers and rubbers, it acts as the feedstock behind 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane—the peroxide crosslinker most commonly applied to polyethylene, ethylene copolymers, and silicone rubber. Additional downstream uses cover polyether rubber and polyurethane polyols.
On the agrochemical side, it serves as a notable intermediate in the chrysanthemic-acid pathway to pyrethroid insecticides and appears in selected herbicide and defoamer products.
In fragrance and fine-chemical applications, it enters synthetic-musk preparation and functions as a structural scaffold for six- and seven-membered heterocyclic boron compounds, surfactants, and mastic adhesives.
