That is an industry position, not a regulator finding, and it should be read as one.
The substitution problem is real at the reagent level too. The ACS Green Chemistry Institute Pharmaceutical Roundtable’s 2026 call for TFA replacements seeks alternatives that mimic TFA’s efficacy in cleaving common acid-sensitive protecting groups and in UPLC purification while retaining its resolving power, and references ultra-low loadings for cleavage operations, implying current usage sits at higher, non-catalytic levels (the ACS GCIPR call for TFA replacements, 2026). TFA is under regulatory scrutiny, not banned.
