What do chloro-hydrocarbons mean on Mars?

What do chloro-hydrocarbons (organochlorides) mean on Mars? 

Apparently the Curiosity teams have announced finding organochlories on Mars. 

I suppose I'm not surprised that they found some simple organic (carbon-containing) compounds on Mars.  Methane, of course, has been observed in the atmosphere for years. 

It would seem like the organic chlorides would be very reactive, at least in some situations.  Is this important for abiogenesis?

It doesn't address your question, but there is a bit more here about methane.

You may find this research relevant.

Some chlorine was contained within a series of chlorohydrocarbons at levels that exceeded instrumental background. It is suggested that perchlorate chlorine has combined with organic carbon from a terrestrial derivatizing agent carried to Mars with the space-craft, but martian or meteoritic sources of organic carbon,which can be collectively termed indigenous, are also possibilities.

Sephton, M.A. & Carter, J.N. "Statistics Provide Guidance for Indigenous Organic
Carbon Detection on Mars Missions" Astrobiology Volume 14, Number 8, 2014

The paper's references will lead you to many more discussions on the topic.
