Definition
material entity that is made primarily of one kind of molecular entity, allowing for minor impurities
Explanatory Notes
A chemical substance material is a material entity whose identity is based primarily on being made of molecular entities of one chemically specified kind. The term does not require absolute purity. Minor impurities may include trace contaminants, residual water, dissolved gases, degradation products, residual process chemicals, or other low-level material present below the level at which the material is treated as a mixed material for the applicable modeling purpose. Materials whose identity depends on the joint presence of multiple compositionally relevant constituents, such as solutions, culture media, buffers, formulations, and hydrolysates, should be modeled as mixed materials.
Examples
- a portion of water; a lot of Water for Injection; a sodium chloride raw material; a glucose powder; an L-glutamine powder; portion of CO2 gas; portion of crystalline sucrose
Counter-Examples
- a 70 percent ethanol solution; phosphate-buffered saline; a chemically defined culture medium; a glucose powder blend containing compositionally intentional excipients; air; polymer composite

Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
There are insufficient constructs to create a set of necessary and sufficient conditions.
Formal Axioms
First-Order Logic Axioms
ChemicalSubstanceMaterial(x) → MaterialEntity(x) ∧ ∃m (MolecularEntity(m) ∧ isMadeOfAtAllTimes(x, m))
Semi-Formal Natural Language Axioms
if x is a ‘chemical substance material’ then x is a ‘material entity’ that ‘is made of at all times’ some ‘molecular entity’
