Description
TCI D2720 1,2-Decanediol is a vicinal diol built on a ten-carbon chain, carrying two hydroxyl groups at the end of that chain in the 1 and 2 positions. The compound belongs to the group of non-heterocyclic building blocks that are used most frequently, because its structure is simple yet highly versatile. In the laboratory, this material serves as a starting material for the preparation of nonionic surfactants, as a chain-building component in polymers, and as a test substance in formulation studies that require a molecule with clearly separated hydrophilic and hydrophobic portions.
The characteristic that makes this material such a common choice is its balanced amphiphilic nature. The octyl chain at the nonpolar end provides affinity for the oil phase, while the 1,2-diol head supplies two hydroxyl groups capable of hydrogen bonding with water. The primary hydroxyl group at position 1 reacts more readily than the secondary hydroxyl at position 2, so researchers can design selective reactions such as esterification, etherification, or tosylation on a single group only. The 1,2-diol motif can also be converted into cyclic acetals, epoxides, or carbonyl compounds through bond cleavage, which opens up a broad range of synthetic routes.
Laboratories in Indonesia typically call on this building block where a molecule with a distinct hydrophilic head and hydrophobic tail is required. Its role covers exploratory synthesis in which one hydroxyl group is modified while the other is retained, preparation of surfactant intermediates, and formulation work carried out on a bench scale. Because the compound is supplied by TCI within the chemistry catalogue as a non-heterocyclic building block, it fits routine research and development activities as well as teaching and method-development work.
Laboratory Applications
- Nonionic surfactant synthesis — the separated hydrophobic octyl tail and hydrophilic 1,2-diol head give the molecule the amphiphilic architecture that surfactant preparation depends on.
- Polymer chain building — the two hydroxyl groups allow the molecule to be incorporated as a chain-building unit, contributing a long alkyl segment to the resulting polymer backbone.
- Selective functionalisation studies — the more reactive primary hydroxyl at position 1 lets researchers carry out esterification, etherification, or tosylation on one group while leaving the secondary hydroxyl untouched.
- Formulation research — the clearly separated hydrophilic and hydrophobic portions make this a useful test substance in formulation studies that need controlled interaction between aqueous and oil phases.
- Conversion to other functional motifs — the 1,2-diol unit can be transformed into cyclic acetals, epoxides, or carbonyl compounds by bond cleavage, supporting multi-step synthetic route development.

Handling and Storage
Store the container tightly closed in a cool, dry, and well-ventilated area, away from direct sunlight, heat sources, and incompatible materials such as strong oxidising agents. Keep the material in its original manufacturer container, or in a clean, chemically compatible and clearly labelled vessel if transferred, and close it immediately after use so that the contents remain free of moisture and contamination. Handle in a fume hood or a well-ventilated workspace while wearing safety goggles, chemical-resistant gloves, and a laboratory coat. Avoid contact with skin and eyes and avoid breathing any vapour or mist. Always consult the manufacturer's safety data sheet before use, and follow institutional procedures for waste collection and disposal.
