Methylthymol blue, trituration 1,100 with KNO3

Methylthymol blue is a pharmacopoeia-quality reagent (Reag. Ph. Eur., Chapter 4.1.1, 1158501) supplied as a trituration 1,100 with KNO3. The preparation has a density of 2,1 g/cm³ and is packed as 50 g in plastic. It belongs to the Reagents 4.1.1 group used with reagents and volumetric standard solutions (Ph. Eur.) in analytical and quality-control laboratories. The trituration with potassium nitrate (KNO3) corresponds to the form given for this Ph. Eur. reagent, so the material can be used where a methylthymol blue trituration 1,100 with KNO3 is specified. UN number 1486 is stated for the product. This 50 g plastic pack from manufacturer Carl ROTH offers a convenient quantity for preparing pharmacopoeial reagents and related laboratory mixtures. Density data of 2,1 g/cm³ help identify and handle the trituration in routine work. Laboratories following European Pharmacopoeia methods can match Chapter 4.1.1 and reference 1158501 when selecting methylthymol blue in this triturated form. The plastic 50 g presentation keeps the reagent available for repeated small-scale preparations consistent with the declared composition and pharmacopoeial listing.
