Amino Compound

Definition & Classification

Amino Compounds are organic/inorganic molecules containing the amino group (–NH₂) or its derivatives.

Type	General Formula	Example	Key Feature
Amines	R–NH₂	Methylamine (CH₃NH₂)	Basic, nucleophilic
Amino Acids	H₂N–R–COOH	Glycine (H₂N–CH₂–COOH)	Zwitterionic at neutral pH
Amides	R–CO–NH₂	Acetamide (CH₃CONH₂)	Less basic than amines
Ammoniates	[M(NH₃)ₓ]ⁿ⁺	Tetraamminecopper(II) [Cu(NH₃)₄]²⁺	Metal-ligand complexes

Key Functional Groups

Group Name	Structure	Example Compound	Polarity/Basicity
Primary Amino	R–NH₂	Aniline (C₆H₅NH₂)	Polar, weakly basic (pKb ~9)
Secondary Amino	R₂NH	Dimethylamine [(CH₃)₂NH]	More basic than primary
Amido	R–CO–NH₂	Urea (NH₂CONH₂)	Neutral in water

Properties & Reactivity

Basicity:Amines > Ammonia > AmidesAromatic amines (e.g., aniline) are less basic due to resonance.Solubility:Low-MW amines (C1–C3) are water-soluble; higher homologs are lipid-soluble.Reactions:Amines: Form salts with acids (e.g., HCl → RNH₃⁺Cl⁻).Amides: Hydrolyze to carboxylic acids + NH₃ under acid/base conditions.

Industrial Applications

Compound Class	Application	Example Use
Amines	Pharmaceuticals, agrochemicals	Epinephrine (adrenaline), herbicides
Amino Acids	Food additives, biopharmaceuticals	L-Glutamate (MSG), insulin production
Amides	Polymers, solvents	Nylon-6,6, DMF (dimethylformamide)
Ammoniates	Catalysts, fertilizers	Haber process (NH₃ synthesis)

Safety & Handling

Compound Type	Hazard	Precaution
Volatile Amines	Corrosive, foul odor (e.g., (CH₃)₃N)	Use fume hood, sealed containers
Aromatic Amines	Carcinogenic (e.g., benzidine)	PPE (gloves, respirator)
Concentrated NH₃	Severe burns, inhalation risk	Store in pressurized cylinders
