Looking for a way to filter out duplicates and sort entries

Hello Everyone,

I will try to describe this as best as I can, but I find it difficult to explain.

I have a few columns of interest here:
Column B is Chemical Identifier Numbers
Column N is a category based on the use of them chemical (ranging 1-12 but excluding 8 and 11)
Column K is the percentage of use that is reported.

Right now I have written a formula that calculated the maximum value from Row K based on the numbers in row B and N.

=MAX(IF(B$2:B$87959=B2, IF(N$2:N$87959=N2, K$2:K$87959)))

and that output is located in Column O. Now I want to find a way to cut the excess and organize my sheet.

Here is an example of what it looks like now. You can see that for the material 123-45-6789, it has multiples in Column N but the values in column O are the same due to the formula I inputted above

_____B________N_____O

123-45-6789____4____0.5%
123-45-6789____4____0.5%
123-45-6789____3____0.1%
123-45-6789____4____0.5%
123-45-6789____1____0.09%
123-45-6789____4____0.5%
123-45-6789____2____0.35%
123-45-6789____2____0.35%
123-45-6789____4____0.5%
123-45-6789____5____0.41%
123-45-6789____5____0.41%
123-45-6789____5____0.41%
123-45-6789____6____0.29%
123-45-6789____4____0.5%
123-45-6789____3____0.1%
123-45-6789____5____0.41%
123-45-6789____4____0.5%
123-45-6789____6____0.29%

And this is what I am hoping to get.

All new columns here
123-45-6789____1____0.09%
123-45-6789____2____0.35%
123-45-6789____3____0.1%
123-45-6789____4____0.5%
123-45-6789____5____0.41%
123-45-6789____6____ 6 0.29%

Is there any way to do this?
