Abstract
15,755. Farbwerke vorm. Meister, Lucius, & Br³ning. Oct. 25, 1911, [Convention date]. [Addition to 15,658/12.] Homologues of methylsulphites of aminoantipyrine are produced by the action of homologues of formaldehyde bisulphites, such as acetaldehyde and propylaldehyde bisulphites, upon aminoantipyrine. The products may be purified by a method analogous to that described in Specification 15,758/12 and may be used in medicine.
