What is an English adjective describing properties related to the content

Is there any single-word adjective that emphasizes the property is related to the content opposed to the properties that are related to the container?

I have seen the word contentual which does not seem to be very common.

To clarify my intent, consider a container that holds liquid. consider the weight of the compound, it is mostly related to the content so, you may say:

weight is a contentual property

on the other hand, the volume, is mostly related to the container, so, it is not a contentual property.

I am looking for a word to replace contentual in the above sentences

Solution 1:

(Nett) weight is a content-related / content-bound property.

I would avoid contentual, unless you define it for your readers. The things described in the OED citations seem more abstract than physical. There is no adjective such as *containeral that would come to mind to help grasp the meaning of contentual, and it might even be confused with contentious.

You say "...consider the weight of the compound, it is mostly related to the content...". In fact, we distinguish gross, nett, tare, and volumetric weight. Nett weight is a property of the contents. Both the container and its contents have weight/a weight.

We also say the container has a certain (maximum) volume; its contents occupy all or a fraction of it. Both the container and its contents have volume/a volume.

If you need to distinguish, I suggest:

container-related properties and content-related properties

An alternative would be content-bound and container-bound properties.

You could also use content and container attributively: "X is a content property and Y is a container property."
