Industrally, glutaraldehyde can be obtained by hydrolysis of the intermediary product (2-ethoxy-3,4-dihydro-2H-Pyran CAS 103-75-3), in the presence of acidic catalyst, which is got by Diels-Alder reaction between ethyl vinyl ether (CAS 109-92-2) and acrolein (CAS 107-02-8).


A glutaraldehyde solution of 0.1 % to 1.0 % concentration may be applied for system disinfection and as a preservative for long term storage. Also used in biological electron microscopy as a fixative. Glutaraldehyde is sometimes employed in the tanning of leather. Frequently used in biochemistry applications as an amine-reactive homobifunctional crosslinker. A solution of 10 % w/w glutaraldehyde is sold under the name "Diswart Solution" to remove common and plantar warts.
