    en.wikipedia.org/wiki/4,4...

    4,4'-Diaminodicyclohexylmethane is the name for organic compounds with the formula CH 2 (C 6 H 10 NH 2) 2.It is classified as a diamine.In the epoxy industry it is often referred to as PACM, short for para-diamino­dicyclohexyl­methane.

  3. Diazald - Wikipedia

    en.wikipedia.org/wiki/Diazald

    Diazald (N-methyl-N-nitroso-p-toluenesulfonamide) is used as a relatively safe and easily handled precursor to diazomethane, which is toxic and unstable. [2] Diazald has become the favored commercially available precursor for the synthesis of diazomethane, compared to reagents like N-methyl-N-nitrosourea and N-methyl-N'-nitro-N-nitrosoguanidine, which are less thermally stable and more toxic ...

    It is a water white liquid at room temperature and is manufactured in relatively small quantities. It is also known as 4,4'-methylenedi(cyclohexyl isocyanate) or methylene bis(4-cyclohexylisocyanate) [2] and has the formula CH 2 [(C 6 H 10)NCO] 2.

  6. Bis-tris methane - Wikipedia

    en.wikipedia.org/wiki/Bis-tris_methane

    Bis-tris methane, also known as BIS-TRIS or BTM, is a buffering agent used in biochemistry. Bis-tris methane is an organic tertiary amine with labile protons having a pKa of 6.46 at 25 °C. It is an effective buffer between the pH 5.8 and 7.2. Bis-tris methane binds strongly to Cu and Pb ions as well as, weakly, to Mg, Ca, Mn, Co, Ni, Zn and Cd ...

  7. Bis-tris propane - Wikipedia

    en.wikipedia.org/wiki/Bis-tris_propane

    Bis-tris propane, or 1,3-bis(tris(hydroxymethyl)methylamino)propane, also known as BTP, is a chemical substance that is used in buffer solutions. It is a white to off-white crystalline powder that is soluble in water. It has a wide buffering range, from 6 to 9.5 due to its two pK a values which are close in value.

    Bistriflimidic acid. The conjugate acid of bistriflimide, which is frequently referred to by the trivial name bistriflimidic acid (CAS: 82113-65-3), is a commercially available superacid.

  9. Diazo - Wikipedia

    en.wikipedia.org/wiki/Diazo

    Diazo compounds have two main Lewis structures in resonance: R 2 >C-–N + ≡N and R 2 >CH=N + =N-. In organic chemistry, the diazo group is an organic moiety consisting of two linked nitrogen atoms at the terminal position.
