I think thats what it is. Looks a bit like a tap connector with the tap

Whats this used for?

For draining the contents of your pipework into a convenient receptacle.

I'm currently doing some work under the kitchen sink and it seems the
only way is to cut further back on the pipe thus losing this valve. Is
this a bad idea ??

I'm guessing that your main stopcock is just below this drain cock, am I
right? AFAIK it's a now waterboard regulation that a drain cock is
fitted above the stopcock, so I guess apart from anything else you'd be
breaking a bye-law by removing it. Why do you want to, anyway?
