Description générale
BDE No 99 is a polybrominated diphenyl ether pollutant, having low acute toxicity. It can be commercially used as a flame retardant additive in building materials, textiles, plastics, and electronic equipments.
Application
BDE No 99 may be used as an analytical reference standard for the determination of the analyte in:
- House dust samples using isotope dilution method combined with liquid chromatography coupled to negative ionization atmospheric pressure photoionization tandem mass spectrometry (LC-NI-APPI-MS/MS).
- Adipose tissue samples using gas chromatography coupled to ion-trap mass spectrometry (GC-IT-MS/MS).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Autres remarques
The customer needs to make sure that the standard is homogeneous, this can be achieved by shaking, vortexing , or sonicating the ampoule before opening the ampoule. Care should be taken when opening the ampoule to avoid any injuries from the broken glass.
The standard should be transferred to a clean and appropriate vial or flask using clean pipettes or micro pipettes. The vial should be immediately capped to avoid any loss or evaporation of the solvent.
After opening the ampoule, the standard should not be stored or kept in the ampoule. To preserve the integrity of the product, the standard should be transferred to an appropriate vial that must be capped and stored according to the recommendation on the Certificate of Analysis.

Prenatal exposure to polybrominated diphenyl ethers (PBDEs) has been associated with cognitive deficits and behavioral problems in children. To date, no study has examined this exposure in association with neurobehavioral development in infants younger than 12 months assessed with observational tasks.

Substances that accumulate to hazardous levels in living organisms pose environmental and human-health risks, which governments seek to reduce or eliminate. Regulatory authorities identify bioaccumulative substances as hydrophobic, fat-soluble chemicals having high octanol-water partition coefficients (K(OW))(>/=100,000). Here we show that
