· Limit test for heavy metals The limit test for heavy metals is designed to determine the content of metallic impurities that are coloured by hydrogen sulphide or sodium sulphide under the condition of the test should not exceed the heavy metal limits given under the individual monograph. The heavy metals (metallic impurities) may be iron, copper, lead, nickel, cobalt, bismuth, antimony etc ...
· At 298 K ion conducting mixed antimonate Na Ni Sb O 2 exhibits an O3type structure, with sodium ions in a distorted octahedral coordination, space group R3m, a = (1)Å, c = (4)Å. 23 Na NMR at 197–288 K reveals two main types of sodium atoms in the structure, ascribed to 18g and 3b positions. The temperature increase results in the sites averaging and NMR .
· For other nitrosamine impurities not listed in table 1, the principles outlined in ICH's M7(R1) guideline8 are recommended to be used to determine an acceptable Intake. As a result of investigations into the presence of nitrosamines, it is apparent that a complete consideration of potential nitrosamine contamination in an FPP must be broader than whether sources of amines and nitrites are ...

The method enables to determine sodium chlorate at the level of 50150 mg/L in a matrix of 13 M sodium hypochlorite. It is based on a rather complex quantitative masking of hypochlorite in the medium of borate buffer at pH by a potentiometric titration with sodium sulfite with further removal of its excess by means of triiodide and finally I 2 formed is removed with thiosulfate.
Canagliflozin is sodiumglucose cotransporter2 inhibitors work by inhibiting SGLT2 to prevent reabsorption of glucose and facilitate its excretion in urine. Impurities in pharmaceuticals which are unwanted chemicals that remain with the active pharmaceutical ingredients (APIs), or develop during stability testing, or develop during formulation or upon aging of both API and formulation.

· UPDATE ON NITROSAMINE IMPURITIES Background Medicine Regulatory Authorities first became aware of the presence of the nitrosamine impurity, Nnitrosodimethylamine (NDMA), in products containing valsartan in July 2018. Valsartan is an Angiotensin II Receptor Blocker (ARB) and belongs to a family of analogue compounds commonly referred to as the sartans.
A method for separating and determining rebeprazole sodium and impurities thereof through high performance liquid chromatography (HPLC) comprises: setting the chromatogram conditions, specifically taking octadecylsilanebonded silica gel as a filling agent, taking ammonium acetate solutionmethanol as a mobile phase, setting the detection wavelength to be 210310 nm, setting the column ...
Antimony is usually delivered to a polymer as the trioxide, but the pentoxide and also sodium antimonate are also used. The pentoxide is more expensive to produce, but can be made in much smaller particle size, which is important for some appliions. The antimonate is used where a watersoluble product is required. Flame Retardant ...
· Sodium antimonate compounds and a sodiumcontaining calcium antimonate crystal were found in the opaque white glass on bead 10/108. These crystals likely formed due to the low lime content of the glass and the substitution of sodium for calcium during crystallization of the opacifier. Though the formation of this compound is likely accidental, the raw materials used or the .
