BDO & Derivatives

The BDO & Derivatives Sector Group

The BDO & Derivatives Sector Group deals with 1,4 butanediol (BDO), and its downstream  products such as gammabutyrolactone (GBL), tetrahydrofuran (THF), N-methylpyrrolidone (NMP), N-ethylpyrrolidone (NEP) and 2-pyrrolidone (PYR).   The group takes care of the regulatory environment of these chemicals and strives to maintain a high level of product safety by appropriate measures. This includes a social responsibility for potential misuse of these bulk chemicals.

Uses and properties

BDO, GBL and PYR, predominantly serve as building blocks in the production of other chemicals or engineering plastics and polyurethane systems (e.g. golf balls, skateboard wheels, car bumpers). THF, NEP and NMP are essential process solvents in the production of circuit boards, insulated wire, membranes and lithium ion batteries. Furthermore they are solvents for inks, lacquers, adhesives and chemical synthesis of pharmaceutical active ingredients THF, apart from its solvent use, is the monomer of Poly THF the principal material for the manufacture of elastic fibers and other high performance polymers.

Issues and regulations


The BDO and Derivatives REACh Consortium activities and dossiers are managed by ReachCentrum.

Voluntary Product Stewardship Code for BDO and GBL

and GBL are on the Voluntary Monitoring List for Non-Scheduled Drug Precursors under the EU regulations on monitoring of trade in drug precursors.  The members of the BDO & Derivatives Sector Group have all committed to a common voluntary Product Stewardship code with measures to prevent the misuse of BDO and GBL and only supply these products to credible customers with known and understood end-uses. The code was introduced in 2005 and is reviewed for effectiveness on a regular basis.
In November 2016, the BDO & Derivatives Sector Group organized a workshop on the voluntary Product Stewardship code for distributors and downstream users of BDO and GBL. The purpose of the workshop was to train distributors and downstream users on the purpose and the content of the Product Stewardship code, collect feedback for further optimization of the code and engage distributors and downstream users in the implementation of the code along the full Supply Chain.
