Forms: 1800s– phloroglucin, 1800s– phloroglucine.

Origin: A borrowing from German. Etymon: German Phloroglucin.

Etymology: < German Phloroglucin (H. Hlasiwetz 1855, in Ann. der Chem. u. Pharm. 96 120) < phloro- phloro- comb. form + ancient Greek γλυκύς sweet (see gluco- comb. form) + German -in -in suffix¹. Compare French phloroglucine (1865 or earlier). Compare indiglucin n.

1862 H. Watts tr. L. Gmelin Hand-bk. Chem. XV. 66 Phloretin boiled with potash-ley is resolved into phloretic acid and phloroglucin.

1879 Jrnl. Amer. Chem. Soc. 1 338 The reaction consists in the production of a cinnabar-red precipitate, when a trace of phloroglucine is added to a solution of nitrate of aniline or toluidine.

1912 R. Whymper Cocoa & Chocolate xx. 208 The same author recommends the estimation of pentosans by a method with phloroglucine.

1933 S. W. Cole Pract. Physiol. Chem. (ed. 9) xiii. 318 To 5 cc. of urine add an equal volume of strong hydrochloric acid and a little phloroglucin (a piece about the size of a pea) and heat the mixture on a boiling shower bath.
