Is this an Emperor?

Recently bought it ,but donno if this is an Emperor so kinda scared to handle it.

. . .

A picture might make this easier for us.

But if it's big and black and has beefy chela, it's probably safe to handle.

Yes and it's not adult.

Imma go with venom on this one.

its 4.5 inches in length without stretching its tail.And any tips how to tell its sex?

Show us a photo of the pectines. There's a sexing subforum here.

Definetly a Pandinus Imperator, I'm gonna go with sub-adult due to the telson color.

defo imperator. if you look underneath it in a plastic container then you will see its pectines. oh, and please dont handle it. it just puts you and the scorp at risk and in the end one of you will get hurt if you frequently handle it...
im not saying it cant be done, and it comes in handy to know how to if you need to move one and dont have a container handy, but it should only be done if neccecary as they will not become tame, just stressed.
bla bla bla...rant rant rant... ect ect... welcome to the forum!

It looks well like a Emperor..
Let it be for a week or two before u start handling it.
You could use a thong to pick it up by it's tail, but apply no pressure as u do not want it to struggle. As u lift it up, place your palm right underneath it and let it do it's thing ~ crawl!
words of comfort : scorpions don't sting on surface that it walks on
good luck trying!!
