With over 65 years experience in the manufacture of complex organic intermediates and more than 30 years at the forefront of speciality chemical production Pentagon is recognised worldwide as leader in the supply of molecules for use in life science and other advanced markets.
Working in close collaboration with our customers we offer bespoke development and manufacturing services as well as an extensive range of high quality multi-application products centred on combining a commitment to operational excellence with strengths in core technologies of: benzylation, bromination, chlorination, Grignard reagents, maleinisation, phosgenation, sodium dispersion and Vilsmeier-Hack chemistry.
Wherever possible we seek to build secure, long term partnerships enabling the identification, development and production of new molecules to be backed with a guarantee of the highest levels of service, reliability and trust. From single stage reactions to innovative multi-stage synthesis our products can be found in many of todays cutting edge applications including: agents for paper sizing, corrosion inhibitors for oil exploration, detergents & lubricants for improved engine efficiency, as well as catalysts for petrochemical refining, advanced intermediates for world leading cardiovascular and HIV drugs, herbicides, and finally active insecticides and rodenticides.
Reflecting the need for consistent high quality, exacting standards of health and safety allied to minimal environmental impact both of our sites are accredited to the international BS EN ISO 9001 and BS EN ISO 14001 standards. Moreover as part of our commitment to a culture of continuous improvement we actively pursue opportunities to reduce waste in all its forms – from fully integrated new product introductions minimising time to market through process improvements increasing process productivity and robustness, eliminating waste and reducing cost onto managing customer supply chains removing unnecessary stock movements, lowering transport costs and diminishing environmental impact.
