Melamine formaldehyde is affected by alkalis and concentrated acids–such as sulphuric acid (H2SO4) and oxalic acid (H2C2O4). Melamine formaldehyde utensils are not microwave safe. They absorb radiation, which causes their polymer bonds to break down and percolate toxins into the food. Melamine for...
It can also react very exothermically and possibility of spitting with halogens and strong acids. In an alkaline environment, the compound is likely to react violently. In addition, the compound can form toxic products such as n-nitrosamines when combined with nitrous acid as well as oxygen, ...

Only two long-chain perfluoro alkyl acids (PFAAs) have been registered with a full registration (salts of perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA)). The manufacture of both substances has been ceased. With the release of the new substance list in August 2022, 14 ...
It has been utilized in peptide synthesis, crosslinking proteins to nucleic acids as well as preparation of immunoconjugates. Water soluble condensing reagent. EDAC is generally utilized as a carboxyl activating agent for amide bonding with primary amines. In addition, it will react with phosphate ...
The authors note that foodborne HMF is a potential hazard and can easily form adducts with amino acids in foods during temperature processing or during the digestion process. They conclude that HMF is prone to reactivity to pH changes and that the level of gastrointestinal absorption is not fully...
