Reinecke Chem.|ˈraɪnɛkə| The name of A. Reinecke, 19th-c. German chemist, used in the possessive or attrib. to designate (a) a red crystalline complex salt, ammonium diamminetetrakis(isothiocyanato)chromate(111), NH4[Cr(NCS)4(NH3)2].H2O, which is used esp. in Biochem. to precipitate large cations, and (b) the parent acid of this salt, H[Cr(NCS)4(NH3)2], which can also be isolated as red crystals. Reinecke described the preparation of the salt in 1863 (Ann. d. Chem. u. Pharm. CXXVI. 113).

Abstr. XXII. 764 The urine is slightly acidified and evapd. to 1/4 its vol., purified with charcoal, and the creatinine pptd. with Reinecke Salt. 1928Brit. Chem. Abstr. A. 542/2 The mixed potassium ammonium salt of Reinecke's acid, obtained by melting together potassium dichromate and ammonium thiocyanate. 1933Biochem. Jrnl. XXVII. 157 Reinecke's salt, [(NH3)2Cr(CNS)4]NH4, is proving to be a valuable precipitant for a variety of basic substances, and its use is likely to extend. 1935Org. Syntheses XV. 75 The undissolved residue from the second extraction consists chiefly of Morland salt (the guanidine salt of the Reinecke acid). 1965tr. Hein & Herzog in G. Brauer Handbk.

II. xxvi. 322 The anion of Reinecke's salt..and that of K2PtCl6 are used to precipitate large organic cations. Hence reineckate |ˈraɪnəkeɪt| [ad.

Its solution gives precipitates with the heavy metals and organic bases, alkaloids yielding characteristic crystalline compounds—reineckates. 1955J. A. Lovern Chem. Lipids of Biol. Significance ii. 61 Choline is estimated in a variety of ways. The simplest and most frequently used methods depend on the formation of a sparingly-soluble complex with the reineckate radical. 1957Jrnl.
