In accordance with section 7.04 (c) of the 2015–2020 Rules and Procedures of the Council of Experts, this is to provide notice that the Non-Botanical Dietary Supplements Expert Committee intends to revise the Valine monograph.

The Expert Committee proposes to revise the Valine monograph with a new, improved High Performance Liquid Chromatographic (HPLC) procedure developed by the USP laboratories for the Related Compounds test to replace the current HPLC procedure that has been postponed due to compliance issues.

It is anticipated that the proposed revision will be published as an Interim Revision Announcement (IRA) in Pharmacopeial Forum 43(2) [Mar.–Apr. 2017] pursuant to section 7.02 of the Rules and Procedures. The comment period for this revision ends on May 31, 2017. In the absence of any adverse comments the proposed IRA will become official on September 01, 2017.
