![]() Under acidic or basic conditions, DMF is known to disproportionate to carbon monoxide and dimethylamine.ġ) Patent Reference: WO2016011390, page 126, (20.2 MB)Ģ) Patent Reference: WO2015088045, page 146, (10.3 MB)ģ) Patent Reference: WO2016014463, page 93, (6.7 MB)Ĥ) Patent Reference: WO2014149164, page 261, (23.7 MB)ħ) Anderson, N. COMPARITIVE STUDY OF US DMF V/S EDMFs Confidentiality Confidentiality of info in DMF is covered by 21 CFR 314.430 (g) and is the same as other type of submissions DMF holder and their customers can reach their own agreements about information sharing There are no Open and Closed part of a DMF in the US, as there are. Runaway reactions have taken place between NaH and DMF. Mixtures containing DMSO1, TFE2 or HFIP3 have be employed when aggregation of the resin peptide hinders reactions. This can be dangerous, especially on large scale. Methylene chloride (DCM), N-methylpyrrolidone (NMP), N,N-dimethylformamide (DMF) and N,N-dimethylacetamide (DMA) are the commonly utilized solvents in solid phase peptide synthesis. Reactions using NaH in DMF can have sudden exotherms. A closely related solvent is dimethylacetamide ( DMA).Ĭatalytic reagent used with oxalyl chloride to convert carboxylic acids to acid chlorides DMF is also used as a reagent in some reactions. The short answer is DMF1 (cheap, non-volatile, dissolves reactants, swells resins), but needs to be fresh (fee of DMA) NMP2 (occasionally, sometimes in combination with DMF - more stable. ![]() Dimethylformamide (DMF) is a polar aprotic solvent with a high boiling point (153 C).
