Dodecanedioic acid (DDDA) is a dicarboxylic acid with the formula (CH 2) 10 (CO 2 H) 2. A white solid, the compound finds a variety of applications ranging from polymers to materials. The unbranched compound is the most commonly encountered C12 dicarboxylic acid.
Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is significantly less volatile than simpler phenolic antioxidants such as butylhydroxytoluene (BHT). This makes it more suitable to stabilising plastics, as it is not driven out by the high temperatures experienced during plastic extrusion and moulding, [2] when they are heated to 150-320 °C (300–600 °F).

Trimethylolpropane triglycidyl ether (TMPTGE) is an organic chemical in the glycidyl ether family. [2] [3] It has the formula C 15 H 26 O 6 and the IUPAC name is 2-[2,2-bis(oxiran-2-ylmethoxymethyl)butoxymethyl]oxirane, and the CAS number 3454-29-3.
The hydrocarbon group is a 4-(1,1,3,3-tetramethylbutyl)-phenyl group. Triton X-100 is closely related to IGEPAL CA-630 , which might differ from it mainly in having slightly shorter ethylene oxide chains.
It has the CAS number 68609-97-2 but the IUPAC name is more complex as it is a mixture and is 2-(dodecoxymethyl)oxirane;2-(tetradecoxymethyl)oxirane;2-(tridecoxymethyl)oxirane. [4] Other names include dodecyl and tetradecyl glycidyl ethers and alkyl (C12-C14) glycidyl ether.
Di-tert-butyl dicarbonate is a reagent widely used in organic synthesis. [1]Since this compound can be regarded formally as the acid anhydride derived from a tert-butoxycarbonyl (Boc) group, it is commonly referred to as Boc anhydride.
