sauerstoffhaltigen

Sauerstoffhaltig is an adjective in German used to describe substances that contain oxygen. The form sauerstoffhaltigen is the declined form used with plural nouns in accusative or dative cases, for example in die sauerstoffhaltigen Verbindungen or den sauerstoffhaltigen Verbindungen. The term is common in chemistry, geology, and biology to indicate oxygen as a constituent element or functional component.

Etymology and usage: The word combines Sauerstoff (oxygen) and haltig (holding, containing). In chemical contexts the label helps distinguish compounds by elemental composition, especially when oxygen is a major constituent or functional group. It is often used descriptively rather than as a strict technical classification.

Examples: Inorganic oxygen-containing compounds include oxides (Fe2O3), sulfates (CaSO4), carbonates (CaCO3), and peroxides (H2O2). In organic chemistry, many functional groups are oxygen-containing, such as alcohols (R-OH), aldehydes and ketones (R-CO-R'), carboxylic acids (R-COOH), esters (R-COOR), and ethers (R-O-R). In biology and materials science, the term describes biomolecules and materials in which oxygen is an essential element.

Notes: The term is primarily descriptive and not tied to a specific oxidation state or reactivity. In German, related terms include sauerstofffrei for oxygen-free contexts. The form sauerstoffhaltigen reflects its grammatical role as the plural, declined adjective form.
