Type of Posting: Publication Correction
Posting Date: 5-Apr-2019

USP recently discovered that for the following monographs, the USP 42–NF 37 version of the file was incorrectly associated with the USP 41–NF 36 publication title and official date. The following monographs and listed DocIDs were published in USP 42–NF 37 with a revision to the <855> chapter reference (see notice here).  

  • Mandelic Acid
    DocID: GUID-5C8F85A6-3418-4479-8BCD-AC4CF9A56174_3_en-US
  • Methylpyrrolidone
    DocID: GUID-205AE5DA-ED0F-4031-A0B4-4271A13DE74E_3_en-US
  • Monosodium Glutamate 
    DocID: GUID-1D1A45E2-B9D5-4D6B-9BAD-BA7B1D07BE6A_3_en-US
  • “Introduction” to the Colorimetric Solutions
    DocID: GUID-13D2C5E6-0A86-4C73-AB0C-D946032E9F19_3_en-US

The versions of the monographs listed above have been reinstated in the USP–NF Online platform and now appear correctly with an official status of “Not Yet Official” and an official date of May 1, 2019 as associated with USP 42–NF 37.

USP apologizes for any inconvenience this may have caused.
