Administrative data

Endpoint:
oxidising liquids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied
Justification for type of information:
In addition the oxygen balance of 1,1"-isopropylidenebis(ethylferrocene), CAS No. 37206-42-1, EC No. 310-202-3 has been calculated.

The Oxygen balance (OB, or OB%) is calculated as follows :-

Oxygen balance = -1600 x [(2.x) + (y/2) – no of oxygen atoms] / molecular weight

If there is a deficiency of oxygen present, the balance is negative, while an excess of oxygen gives a positive balance, and such compounds can act as oxidants.

Therefore, the oxygen balance of 1,1"-isopropylidenebis(ethylferrocene), CAS No. 37206-42-1, EC No. 310-202-3 is as follows:-

The molecular formula of this substance is C27H32Fe2
MW= 468.23

Oxygen balance = -1600 x [(2 x27) + (32/2) - 0] / 468.23

Oxygen balance = -239.2%

The oxygen balance of 1,1"-isopropylidenebis(ethylferrocene), CAS No. 37206-42-1, EC No. 310-202-3 is substantially more negative than -200% indicating that it is unlikely to be an oxidiser.
