一般說明
This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.
Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate.

Chlorbromouron is an obsolete systemic phenylurea herbicide used for pre- and post- emergence control of annual grasses (e.g. foxtail) and broad leafed weeds (e.g. chickweed) on a variety of crops. It inhibits photosynthesis by interfering with the electron transfer in photosystem II. As per the commission regulation no 1107/2009, repealing the council directive 91/414/EEC, chlorobromouron is not approved for use in the European Union. A default maximum residue limit (MRL) of 0.01 mg/kg is set for chlorbromuron as per regulation (EC) no. 396/2005.
