New USP-NF Online, USP 41-NF 36 and Supplements: Cross-reference to Chromatography <621>, Thin-Layer Chromatography

Type of Posting: Publication Correction
Posting Date: 10–Aug–2018

USP recently discovered a technical error that is causing hyperlinks to Chromatography 〈621〉, Thin-Layer Chromatography to incorrectly direct users to the USP monograph for Quinine Sulfate. This affects USP 41–NF 36 and both the First Supplement to USP 41–NF 36 and Second Supplement to USP 41–NF 36 in the new USP-NF Online. A list of all files containing the inaccurate link is attached here.

The links will be corrected in USP 42-NF 37. The links in the legacy USP-NF Online platform are correct. USP apologizes for any inconvenience this may have caused.

Should you have any questions, please contact Caroline Martin, Senior Director, Publications (301-816-8521 or
