EC number: 203-041-4
CAS number: 102-60-3
Estimated half-lives for the components of the substance range from 1.1 to 3.1 hours.
The presented data of CAS 102 -60 -3 are
derived from a read-across to CAS 25214-63-5. Estimated second-order
rate constants for reaction of hydroxyl radical with lowest and
highest-molecular weight homologues of the UVCB substance range from
1.2E-10 to 3.4E-10 cm3/molecule*sec.
Corresponding half-lives range from 1.1 to 3.1 hours, based on a
default hydroxyl radical concentration of 500,000 molecules/cm3. The
longest estimated half-life, associated with the lowest-molecular weight
homologue, is used to represent the atmospheric half-life of all
homologous components of the UVCB substance in the chemical safety
