WebApr 1, 2024 · Phenacetin (p-ethoxyacetanilide) and paracetamol (p-hydroxyacetanilide) are more popular analgesic antipyretics. Phenacetin is structurally similar to paracetamol, and is employed as an additive here, due to its availability and low price with no reported polymorphs and it crystallizes as needle-like form ( Croker et al., 2015 ). WebApr 12, 2024 · In this work, phenacetin (PHEN) was selected as a model compound to investigate the relationship between the solvent and nucleation kinetics. Induction times at different supersaturation in six solvents were measured. FTIR and NMR spectroscopy were employed to explore the solvent–solute interactions and the self-association properties in …
