Potassium carbonate
Potassium carbonate (K2CO3) is a white salt, soluble in water (insoluble in ethanol) which forms a strongly alkaline solution. It can be made as the product of potassium hydroxide's absorbent reaction with carbon dioxide. It is deliquescent, often appearing a damp or wet solid. Potassium carbonate is used in the production of soap and glass. Alternative Names: Dipotassium cabonate. CAS No. 584-08-7. Molecular formula: CK2O3. Mole weight: 138.205. Purity: 99%+. IUPAC Name: Dipotassium;carbonate. SMILES: C(=O)([O-])[O-].[K+].[K+]. InChI: InChI=1S/CH2O3.2K/c2-1(3)4;/h(H2,2,3,4);/q;2*+1/p-2.

Mole weight: 111.14g/mol. IUPAC Name: 1-ethenylpyrrolidin-2-one. SMILES: C=CN1CCCC1=O. InChI: InChI=1S/C6H9NO/c1-2-7-5-3-4-6(7)8/h2H,1,3-5H2.
Polyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R1-(O-CH2-CH2)n-O-R2. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo than their non-PEGylated counterparts, a phenomenon known as PEG shielding. Functionalised PEG lipids and phospholipids can be used for protein-PEG conjugation. Purity: ≥95%.
