1,4-Butanediol, also called Butane-1,4-diol (other names include 1,4-B, BD, BDO and 1,4-BD), [5] is a primary alcohol and an organic compound with the formula HOCH 2 CH 2 CH 2 CH 2 OH. . It is a colorless viscous liquid first synthesized in 1890 via acidic hydrolysis of N,N'-dinitro-1,4-butanediamine by Dutch chemist Pieter Johannes Dekkers, who called it "tetramethylene glyco
2-methylpropane-1,2-diol; 2-methylpropane-1,3-diol; and one unstable geminal diol: 2-methylpropane-1,1-diol (not a glycol), hydrate of 2-methylpropanal (isobutyraldehyde) These three methylpropanediols are structural isomers of butanediols. They are not chiral.
1,4-Butanediol diglycidyl ether (B14DODGE) is an organic chemical in the glycidyl ether family. It is aliphatic and a colorless liquid. It has two epoxide (oxirane) groups per molecule. [1] Its main use is in modifying epoxy resins especially viscosity reduction. [2] It is REACH registered. [3] The IUPAC name is 2-[4-(oxiran-2-ylmethoxy ...
Busulfan (Myleran, GlaxoSmithKline, Busulfex IV, Otsuka America Pharmaceutical, Inc.) is a chemotherapy drug in use since 1959. It is a cell cycle non-specific alkylating antineoplastic agent, in the class of alkyl sulfonates. Its chemical designation is 1,4-butanediol dimethanesulfonate.
1,4-Butynediol is a precursor to 1,4-butanediol and 2-butene-1,4-diol by hydrogenation. It is also used in the manufacture of certain herbicides, textile additives, corrosion inhibitors, plasticizers, synthetic resins, and polyurethanes. It is the major raw material used in the synthesis of vitamin B 6. [5]
It is also used in polyadditions along with 1,4-butanediol to form sulfur-containing polyester and polyurethanes containing diisocyanate. [ 5 ] [ 6 ] [ 7 ] Several of these polymers are considered biodegradable and many of their components are sourced from non-petroleum oils.
A common approach catalytic amounts is excess use of sacrificial organic molecules such as isopropanol or ethanol. This approach, however, leads to stoichiometric amounts of waste. The use of 1,4-butanediol as a smart cosubstrate for cofactor regeneration was the next step towards more sustainable redox biocatalysis (Scheme 1). [1]
It is produced by polymerization of tetrahydrofuran as well as 1,4-butanediol. The product is commercially available as polymers of low average molecular weights , between 250 and 3000 daltons . In this form it is a white waxy solid that melts between 20 and 30 °C.
