Chemische

Chemische is an attributive adjective in German meaning “related to chemistry” or “chemical.” It is derived from the noun Chemie and is used to describe substances, processes, or properties belonging to the science of chemistry. In German, chemische appears before the noun and is declined to match gender, case, and number (for example: chemische Verbindung, chemischer Stoff).

Common usages include chemische Reaktion (chemical reaction), chemische Verbindung (chemical compound), chemische Substanz (chemical substance), and chemische Eigenschaften (chemical properties). The term spans inorganic and organic chemistry, materials science, and related technical fields, and it is widely found in textbooks, safety data sheets, product descriptions, and academic articles.

Notes for learners: chemische is not a noun; it does not stand alone as a name. It should be distinguished from Chemie, which denotes the science itself, and from proper names that may include “Chemische” as part of a title or brand. The form also participates in normal German adjective inflection, with endings changing to agree with the gender, case, and number of the noun it modifies (e.g., chemische Verbindung, chemischen Stoff, chemische Reaktion).
