Description
2,2'-Methylenediphenyl diisocyanate is an aromatic diisocyanate reagent for laboratory chemical research, identified by CAS 2536-05-2. It has the empirical formula C₁₅H₁₀N₂O₂ and a molar mass of 250,26 g/mol. Physical data reported for the substance include a flash point of 193 °C and a boiling point of 379,3 °C, supporting informed handling and process planning at the bench. size suits small-scale synthetic trials, analytical characterisation, and method development where only limited quantities are required. Two isocyanate groups linked through a methylene-bridged diphenyl framework make the compound relevant to isocyanate chemistry, model polymer studies, and specialised organic transformations under controlled conditions. This material is available from manufacturer Carl ROTH within a biochemicals and fine-chemicals selection aimed at research laboratories. Clear CAS, formula, and thermal data help users document protocols and compare specifications across experiments. Standard laboratory precautions for reactive isocyanates should be followed during weighing, dissolution, and transfer. The compact unit offers a practical starting quantity for evaluation and qualification work.

Questions about 2,2'-Methylenediphenyl diisocyanate, 50 mg
What is this article?
2,2'-Methylenediphenyl diisocyanate, 50 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
