I am in Organic Chemistry Lab and I need to find out what an unknown substance is by Wednesday. It is a yellow powder with a melting point about 144-148 and it contains nitrogen. If anyone could give me an idea what it could be that would be awesome since this lab is 20% of my semester grade.

Ok, as far as solubility, that was one of the biggest problems I had. The first test is to test for whether or not it was soluble in water, which mine was. But when I was talking to my teacher about it he said that it should not have been soluble in water and that the pH of the distilled water I was using was causing the problem (?). And since all the other solubility tests call for some type of acid or base dissolved in water, I could no longer use solubility tests to narrow down what group it fell into (nitrides, amindes, amines, etc). When I did a sodium fusion test, it tested positive for nitrogen, so that is how I know that it contains nitrogen.

Anthranilic acid (2-Aminobenzoic acid) is certainly one possibility that fits the meager information you've given us, but it is NOT the only one possible.
What else do you know about it? Solubility? Have you determined what kind of nitrogen it contains -- primary, secondary or tertiary amine; amide; nitro; nitroso?
What about instrumental analysis? What does your IR and/or NMR indicate?
Have you tried making a derivative to confirm your hypothethis?

Its surely is Anthranilic acid.
