Description

Application

Development of Low Sodium Table Butter via Partial Replacement of Sodium Chloride with Potassium Chloride.: This study explores reducing sodium content in table butter by substituting sodium chloride with potassium chloride. The findings are significant for chemists focused on food chemistry and the development of healthier food products with acceptable sensory characteristics (Biointerface Research in Applied Chemistry, 2020).

Application Note

Sodium chloride is supplied in EMSURE® analytical grade for laboratory work requiring a high-purity source of NaCl. This 1 kg pack meets ACS, ISO and Reag. Ph Eur requirements and has an assay of at least 99.5% by silver nitrate titration. The reagent is suitable for preparation of saline solutions, analytical reagents, buffers and ionic-strength adjustments where controlled chloride and sodium purity are important. Its solubility is approximately 358 g/L, supporting preparation of concentrated aqueous solutions. Defined impurity specifications help reduce background contamination in quantitative chemistry, sample preparation and general laboratory workflows that require reagent-grade sodium chloride rather than technical material.
