Description
TCI D2719 erythro-5,6-Dodecanediol is a vicinal diol built on a twelve-carbon chain, carrying two neighbouring hydroxyl groups at the 5 and 6 positions and supplied as the erythro diastereomer with defined stereochemistry. As a non-heterocyclic building block, it connects the world of long-chain chemistry with the demands of careful stereochemical work. In the laboratory, materials of this type are typically used to confirm the outcome of dihydroxylation reactions, to serve as comparison material in instrumental analysis, and as a starting material for the synthesis of lipid molecules and hydroxyl-bearing aliphatic derivatives.
The principal value of this compound lies in the clarity of the relative configuration of its two hydroxyl groups. In the dihydroxylation of alkenes, both erythro and threo products may form depending on the reaction mechanism, so the availability of a pure erythro diastereomer makes it easier for researchers to distinguish which reaction pathway is actually taking place. The long aliphatic chain gives the molecule a mildly amphiphilic character, with a lipophilic hydrocarbon portion and a diol head capable of hydrogen bonding. That combination influences solubility, film-forming ability, and the behaviour of the compound in aqueous as well as solvent-based systems.
In Indonesian laboratories, a material of this kind generally belongs in organic synthesis and analytical work rather than in routine testing. It is used by university research groups, stereochemistry and lipid chemistry laboratories, and industrial R&D units that need a diastereomer of established configuration as a benchmark. Because it is a defined building block rather than a bulk reagent, it is usually handled in small quantities, used deliberately for specific experiments, and recorded carefully in laboratory documentation.
Laboratory Applications
- Verification of dihydroxylation products — provides a stereochemically defined erythro reference so researchers can confirm whether their alkene dihydroxylation gave the expected diastereomer.
- Reference material for instrumental analysis — its established configuration makes it a reliable comparison standard when chromatographic or spectroscopic data must be assigned to a specific diastereomer.
- Starting material for lipid-related synthesis — the twelve-carbon backbone with a diol head suits preparation of lipid molecules and long-chain hydroxylated derivatives in research settings.
- Studies of reaction mechanism and stereoselectivity — the availability of a pure erythro isomer lets investigators separate syn from anti pathways and interpret stereochemical outcomes with confidence.
- Preparation of functionalised aliphatic derivatives — the two adjacent hydroxyl groups offer accessible handles for further transformation into esters, ethers, and other aliphatic building blocks.

Handling and Storage
Store the material in its tightly closed original container, kept in a cool, dry and well-ventilated place away from direct sunlight, heat sources and incompatible chemicals, and follow the storage conditions stated on the manufacturer's label and Safety Data Sheet. Glass containers with well-sealing caps are suitable for transfer and short-term working portions, since the diol head can pick up moisture from humid air. Handle the compound in a fume hood or well-ventilated area using a laboratory coat, safety goggles and chemical-resistant gloves. Use clean, dry spatulas to avoid contaminating the stock, close the container promptly after weighing, label all secondary containers clearly, and dispose of residues and contaminated materials according to your institution's chemical waste procedures.
