USP HS Code 2806 10 00 Physicochemical Information Density 1.00 g/cm3 (20 °C) pH value 1.2 (H₂O, 20 °C) Safety Information according to GHS Storage class 8B Non-combustible, corrosive hazardous materials WGK NWG not water endangering Disposal 28 Aqueous solutions: Container D. Storage and Shipping Information Storage Store at +15°C to +25°C. Transport Information Declaration (railroad and road) ADR, RID UN 1789 , 8, II Declaration (transport by air) IATA-DGR UN 1789 , 8, II Declaration (transport by sea) IMDG-Code UN 1789 , 8, II, Segregation Group: 1 (Acids) Specifications Volumetric solution in accordance to the chapter reagents of the Pharmacopoeia (Ph Eur, USP). Amount-of-substance concentration 0.1000 mol/l The concentration of this volumetric solution was determined with volumetric standard Tris(hydroxymethyl)aminomethane (article number 1.02408). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of ± 0.003 (k=2 coverage factor for 95% coverage probability). The certified value is traceable to primary standard NIST SRM 723e (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard Tris(hydroxmethyl)aminomethane, measured in the accredited calibration laboratory of Merck KGaA, Darmstadt, Germany in accordance to DIN EN ISO/IEC 17025.
