CRMs for Organophosphate Flame Retardants (OPFRs)

Organophosphate Flame Retardants (OPFRs) and the Environment

Organophosphate flame retardants (OPFRs) are additive flame retardants used to reduce flammability in consumer and industrial products such as plastics, textiles, electronics, wire, and building materials to help meet fire safety requirements. Unlike reactive flame retardants, OPFRs are not chemically bonded to materials, allowing them to be released into the environment throughout a product's lifecycle. Human exposure to OPFRs has been linked to adverse health effects, including neurotoxicity, carcinogenicity, endocrine disruption, reproductive toxicity and central nervous system effects. These concerns underscore the importance of environmental monitoring and the development of accurate, reliable analytical methods for their detection.

TCEP, TCPP, and TDBPP are chlorinated and brominated OPFRs. The EPA's Risk Evaluation for Flame Retardant TCEP has found that TCEP leaching from paints and coatings primarily end up in water, sediment, soil or dust and presents unreasonable risk of kidney cancer and noncancer health effects to workers and consumers.

Reference Standards for Organophosphate Flame Retardants

AccuStandard offers a comprehensive range of OPFR Certified Reference Materials (CRMs) to help laboratories achieve accurate, reliable, and reproducible analytical results. CRMs are essential for the accurate identification and quantification of organophosphate flame retardants, supporting instrument calibration, method validation, and quality control.

Why Are OPFRs Used?

OPFRs have become widely used as alternatives to brominated flame retardants (BFRs), particularly polybrominated diphenyl ethers (PBDEs), which have been phased out or banned due to concerns over their persistence, bioaccumulation, and toxicity. Their cost-effectiveness, flame-retardant performance, and compatibility with a wide range of materials have made OPFRs a preferred replacement in many commercial and industrial applications.
