Web1 sep. 1999 · In all urine samples, 0.1 mL of a 0.1 mol/L KMnO 4 solution gave good results. Short reaction times (3 and 6 h) were found to give low results for thiocyanate in some cases, whereas 16 h always gave good results. To check the results at higher thiocyanate concentrations, we added 5–100 mg SCN − /L urine to sample 6. Het thiocyanaat-ion (SCN ) is een anion bestaande uit een stikstofatoom, een koolstofatoom en een zwavelatoom, en is 1 keer negatief geladen. De moleculaire massa bedraagt 58,0824 g/mol. Thiocyanaat is de geconjugeerde base van thiocyaanzuur. In de organische chemie is het ook een functionele groep. De structuurformule, …

Single crystal X-ray structural analysis reveals that NCS− templates assemble dpaH+ units into a 3-D layer structure along the b axis through strong hydrogen bonding. Molecular salt 1 works as an anion-binder …
WebThiocyanate is 100-fold less toxic than cyanide and is excreted by the kidney with an approximate elimination half-life of 2.7 days. Renal insufficiency prolongs elimination. Symptoms of thiocyanate toxicity are primarily neurologic. WebSilver thiocyanate is applied in the preparation of nonmetallic thiocyanates, analytical reagent, in photographic emulsions and as an organic intermediate.
