2-butene-1,4-diol (B2D)
2-butene-1,4-diol (B2D) is a hydroxyl-functional chemical substance or chemical grouping identified by the named structure.

Product & engineering
Understand the product.
1,4-Butenediol is a pesticide and pharmaceutical intermediate, also known as 2-butene-1,4-diol. There are two isomers, both of which are amber odorless liquids. Easily soluble in water, ethanol, acetone, and almost insoluble in lower aliphatic hydrocarbons or aromatic hydrocarbons. Mainly used as a plasticizer for alkyd resins, a crosslinking agent for synthetic resins, and a bactericide, etc. It is also used in the preparation of nylon and medicine.
Positional and stereochemical identity, assay, water content and supplied form distinguish the material. A diol feedstock, formulated resin and finished polymer article have different commercial boundaries.
The commercial boundary
Use the selected edition’s stated product level, geography, years and measurement basis. Materials, components, finished systems and services are separate commercial boundaries unless that edition explicitly combines them.
Which isomer identity and supplied specification define the diol?
Positional and stereochemical identity, assay, water content and supplied form distinguish the material. A diol feedstock, formulated resin and finished polymer article have different commercial boundaries.
