Description Catalogue Number 115480 Synonyms N-Benzyl-N,N-dimethyl-N-[4-(1.1.3.3-tetramethylbutyl)-phenoxyethoxyethyl]ammonium chloride Product Information HS Code 2923 90 00 Physicochemical Information Density 1.0 g/cm3 (20 °C) pH value 9 - 10 (H₂O, 20 °C) Safety Information according to GHS Storage class 10 - 13 Other liquids and solids WGK WGK 1 slightly water endangering Disposal 28 Aqueous solutions: Container D. Storage and Shipping Information Storage Store at +15°C to +25°C. Specifications Amount-of-substance concentration 0.004000 mol/l The molar concentration of this volumetric solution is standardized against sodium dodecyl sulfate (catalog no. 1.12533). The determined titer is 1.000 at 20°C with a measurement uncertainty of ± 0.001. This titer is specific for the method, equipment and conditions of the titration laboratory of the Merck KGaA, Darmstadt, Germany. Note: The titer is a correction factor to correct variations of the volumetric solution, the titration equipment, the temperature and other laboratory conditions. For exact titration results it is recommended to determine a titer with the laboratory specific equipment and conditions directly after opening a bottle of new solution and at regular time intervals.
