(a protein involved in biological processes like tumor progression).
USP 39 is the 2016 official edition of the United States Pharmacopeia and National Formulary, offering public standards for pharmaceuticals. A critical, often accessed section is General Chapter , which outlines permissible limits for elemental impurities in drug products. For the specific text of the chapter, see US Pharmacopeia (USP) 〈232〉 ELEMENTAL IMPURITIES—LIMITS
Mandatory, legally enforceable requirements.
– Overall management of a microbiological control program for environments where the risk of microbial contamination is controlled through aseptic processing
The USP 39 publication includes:
: The official implementation date for <232> and <233> was set for January 1, 2018 , with the heavy metals chapter <231> deleted on the same date. This gave the pharmaceutical industry approximately two years to transition to the new elemental impurities framework.
limits for elements based on how a drug is taken (oral, parenteral, or inhaled). For example, inhaled drugs have much stricter limits for certain metals because they enter the bloodstream faster through the lungs. Official Recognition:
Historically, the USP was distributed via multi-volume printed books and official flash drives containing indexed PDF files. Today, the United States Pharmacopeia has fully transitioned to a secure, cloud-based platform called .
For professionals, students, and researchers in the pharmaceutical industry, accessing the format remains essential for historical compliance, research comparisons, and navigating detailed analytical methodologies. What is USP 39?
Pharmacies involved in sterile compounding often refer to older USP chapters—especially <797>—to show compliance history during FDA or state board inspections.
Each monograph typically includes sections on definition, identification, specific tests or assays, impurity limits, and packaging and storage requirements.
USP 39 contained an important revision to <797> that introduced stricter requirements for beyond-use dating, environmental monitoring, and personnel training. Many pharmacies documented their initial compliance with USP 39’s <797>.
USP 39 continued the ongoing effort to replace older, less reliable Thin-Layer Chromatography (TLC) or titration methods with High-Performance Liquid Chromatography (HPLC) and Ultra-Performance Liquid Chromatography (UPLC). This modernization improved peak resolution, reduced solvent waste, and increased quantification accuracy in quality control laboratories. Accessing USP 39: Understanding PDF and Digital Formats
– Good distribution practices for bulk pharmaceutical excipients
In USP 38–NF 33, the omission of General Chapter <231> Heavy Metals was published with an official date of December 1, 2015. Cross‑references to <231> were removed from individual monographs in USP 38 and USP 39 and following publications, with delayed implementation on January 1, 2018. USP 39 thus represents the edition where the heavy metals phase‑out was fully documented and the elemental impurities framework was finalized in preparation for its 2018 implementation.
The USP sells archived editions, including USP 39, as a bound book or a downloadable PDF for a fee. You can purchase the official PDF from the USP website. Expect to pay between $500–$1,000 for historical editions.
