azotlu

Azotlu is a Turkish adjective meaning "containing nitrogen." In chemistry and related disciplines, it is used to describe substances that include nitrogen atoms. The term encompasses a broad range of materials, from simple inorganic salts to complex organic molecules. It is formed from azot, the Turkish word for nitrogen, with the suffix -lu, meaning "having" or "possessing".

Inorganic azotlu compounds include ammonium salts (for example ammonium chloride), nitrates (such as calcium nitrate), and nitrites (such as sodium nitrite). In these species nitrogen can occur in different oxidation states, from -3 in ammonia to +5 in nitrates. Other azotlu inorganic classes include cyanides (CN−) and certain nitride and oxide systems where nitrogen is present in the lattice or as part of a compound.

In organic chemistry, azotlu compounds cover amines (RNH2), amides (RCONR2), nitriles (RCN), nitro compounds (R–NO2), and nitrogen-containing heterocycles such as pyridine and imidazole. The presence of nitrogen affects properties such as basicity, acidity, polarity, and reactivity, and it is a key factor in the behavior of pharmaceuticals, dyes, and polymers.

Applications and relevance: azotlu compounds are central to agriculture as nitrogen fertilizers; they also appear in materials science, medicine, and environmental chemistry. The nitrogen cycle describes natural transformations of azotlu species through fixation, mineralization, nitrification, and denitrification. Safety and handling vary by compound, as some nitrogen-containing species can be toxic or oxidizing. Detection and analysis rely on elemental analysis, spectroscopy, and, for organic compounds, NMR and mass spectrometry.
