Cytarabine USP Monograph
Posted: Thu Feb 08, 2018 2:41 pm
Hi,
A question on the cytarabine USP HPLC related substances method, which gives a relative response factor of 1.5 for Impurity 1 (RRT 0.38) and Impurity 2 (RRT 0.43).
Does anybody know the identity of these impurities? I can't find any info online - strange that RRFs are provided for impurities whose identities are all but hidden!
Any references would be greatly appreciated,
Thanks in advance
