Cefditoren impurity 6, identified as the cefditoren E-isomer C=C, is a critical chiral reference standard used in pharmaceutical quality control. It represents a specific geometric isomer arising during synthesis or degradation. The molecular formula is C18H20N4O7S2 with CAS No. 193563-67-8.
Store under -20°C in dark, dry conditions to prevent isomerization. Handle with appropriate PPE as it is a synthetic intermediate not intended for direct clinical administration.
