Pharmacopeial Forum 44(3) [May–Jun. 2018]: Eriochrome Black T

Type of Posting: Publication Correction

Posting Date: 06–Jul–2018

USP recently discovered an error with the Eriochrome Black T proposal in Pharmacopeial Forum 44(3) [May–Jun. 2018]. One of the proposed changes was absent from the reagent proposal. The proposed addition "Dilute 10 mL of this solution with water to 1 L." should have appeared after the second sentence in Magnesium standard solution.

USP apologizes for any inconvenience this may have caused. The corrected proposal will post in Pharmacopeial Forum 44(5) [Sep.–Oct. 2018].
