Kimika organikoan 1,4-butanodiola konposatu organikoa da, alkoholen familiakoa, diolen azpifamiliakoa, HOCH2CH2CH2CH2OH formula duena. Likido kolorge likatsua da[1].

Industrian bi bide nagusi erabiltzen dira 1,4-butanodiola prestatzeko[2]:

- Formaldehidoa eta azetilenoa erreakzionaraziz:

- Anhidrido maleikotik abiatuz:

1,4-butanodiola industrian plastiko, zuntz eta poliuretano batzuen disolbatzaile gisa usatzen da.

Poli(butilen tereftalato) polimeroaren sintesian ere baliatzen da. Halaber, tetrahidrofurano disolbatzaile inportantea sintetizatzeko ere erabiltzen da.

1,4-butanodiola olgetarako droga gisa ere usatzen da.
