In the title mol-ecular salt, C(4)H(10)NO(+)·C(4)H(5)O(6) (-), the morpholinium cation adopts a chair conformation. The conformation of the C-C-C-C backbone of the monotartrate anion is close to anti [torsion angle = 173.18 (17)°], which is supported by two intra-molecular O-H⋯O hydrogen bonds. In the crystal, the components are linked by N-H-O and O-H-O hydrogen bonds, generating (001) sheets.

Simple, fast and reproducible methods were developed for the determination of Tolterodine tartrate (TOL), the first method (method A) was based on the oxidation of the drug using permanganate in acidic medium in the presence of methylene blue dye and estimation of (TOL) by measuring the absorbance of the residual amount of methylene blue dye at 600 nm, in (method B) the drug amount was estimate...

Palladium catalysed three component cascade process, involving coupling of 2-iodobenzoates, -benzaldehydes, or acetophenones with substituted allenes and ammonium tartrate as an ammonium surrogate, provides a novel and facile route to substituted functionalised isoquinolinones and isoquinolines in good yields.

Avoiding food that contains toxins is crucial for the survival of many animals, particularly herbivores, because many plants defend themselves with toxins. Some animals can learn to avoid food containing toxins not through its taste but by the toxins' effects following ingestion, though how they do so remains unclear. We studied how desert locusts (Schistocerca gregaria), which are generalist h...

Mild hypnotics are often recommended for young children with sleep problems. This study assesses the efficacy of trimeprazine tartrate in 1 to 3 year old children with persistent and severe night waking in a double blind crossover trial with placebo. Children on treatment with trimeprazine had significantly fewer wakings, less time awake at night, and more night time sleep compared with those o...

Malic dehydrogenase has been shown to catalyze the reduction of diketosuccinate by DPNH (4). Furthermore, both oxaloglycolate and diketosuccinate undergo spontaneous decarboxylation in aqueous solution. These nonenzymatic reactions complicate the analysis of the metabolic path of degradation of tartrate. As a prerequisite for the use of labeled compounds to study the biochemical synthesis and d...

The title compouand {[Zn(C(4)H(4)O(6))(C(12)H(8)N(2))]·6H(2)O}(n), has a linear chain structure parallel to [100] with Zn(C(4)H(4)O(6))(C(12)H(8)N(2)) repeat units; the asymmetric unit consists of one Zn(2+) cation, one l-tartrate dianion, one 1,10-phenanthroline and six free water mol-ecules. The Zn atom is in a distorted octa-hedral ZnN(2)O(4) coordination environment. The crystal structure i...
