Ethyl acetate limit as per ich
WebEthyl acetate ( systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH3CO2CH2CH3, simplified to C4H8O2. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and in the decaffeination process of tea and coffee. Web• According to published list in ICH Q3C , there are 61 solvents. • This list would be a challenge for separation on any single GC phase , as critical coelution will be inevitable. • In ICH guideline, residual solvents are grouped based on their toxicity, both class I and class 2 need to be analyzed by sensitive and specific methodologies.
