Analyse 6PPD and 6PPD-quinone in the environment

From tyre particles to micropollutants: an environmental challenge

Pollution linked to tyre wear is now an emerging source of contamination in aquatic environments. Among the chemical compounds released into run-off water is 6PPD (N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine). It is an antioxidant additive widely used in the manufacture of synthetic rubbers, particularly for vehicle tyres (NR, SBR, BR).

Under the effect ofatmospheric ozone, this compound is transformed into 6PPD-quinone, a molecule recently identified as toxic for certain aquatic species, in particular salmonids. The detection of these substances in water (rainwater and surface water), soil and air has led to the development of new environmental monitoring strategies.

Reference materials for analysis laboratories

In response to this problem, Chiron AS (Zeptometrix) offers a complete range of referencematerials for 6PPD and 6PPD-quinone. These products are tailored to the needs of environmental laboratories wishing to carry out reliable assays, particularly in the context of the EPA 1634method currently being validated.

More specifically, the range includes:

6PPD (CAS 793-24-8) : neat standard (100 mg).
6PPD-quinone (CAS 2754428-18-5) :
- Neat standard (5 mg or 10 mg),
- 100 µg/mL solution in acetonitrile (1 mL).
6PPD-quinone-d5 (CAS 2750119-14-1): isotopically labelled standard, also in pure form or in solution.

These references are designed to ensure traceability, accuracy and compliance with international standards for micropollutant analysis.

A rigorous response to the challenges of tomorrow

In a context where the monitoring of contaminants resulting from human activity, even indirectly, is becoming essential on a global scale. Thanks to the precise, reliable and traceable standards offered by Chiron AS (Zeptometrix), environmental analysis professionals havean essential tool for assessing the impact of these compounds on our ecosystems.

Advantages of Chiron AS standards

Compatibility with environmental regulations.
Products suitable for quantifying 6PPD-quinone in complex matrices (water, soils, air).
Reliability for applications monitoring micropollutants from tyre particles.
