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 Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
