Basic Information
Product Name: Ampicillin
CAS Number: 69-53-4
Alias: D(-)-α-Aminobenzylpenicillin
Molecular Formula: C16H19N3O4S
Molecular Weight: 349.40 g/mol
IUPAC Name: (2S,5R,6R)-6-[[(2R)-2-amino-2-phenylacetyl]amino]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid
Structural Information
- Structure Type: Semi-synthetic penicillin antibiotic, β-lactam compound
- Structural Features: Contains characteristic β-lactam ring and thiazolidine ring, with an aminophenylacetyl side chain. The amino group enhances its antibacterial activity and water solubility.
Physical & Chemical Properties
- Appearance: White to off-white crystalline powder
- Odor: Odorless
- Melting Point: 214–216 °C (decomposition)
- Solubility: Slightly soluble in water; soluble in dilute acid and dilute alkali solutions; practically insoluble in ethanol, ether and non-polar organic solvents
- Stability: Stable under dry sealed conditions. Easily hydrolyzed and inactivated in aqueous solution, especially under high temperature, strong acid or strong alkali. Sensitive to moisture and prolonged light exposure.
Synthesis & Applications
Synthesis Method
Synthesized by acylation reaction of 6-aminopenicillanic acid with D-phenylglycine derivatives. The crude product is purified by crystallization and drying to obtain high-purity finished product.
Main Applications
- Pharmaceutical Field: Broad-spectrum penicillin antibiotic, effective against gram-positive and partial gram-negative bacteria. Widely used for treating respiratory, urinary, gastrointestinal and soft tissue bacterial infections.
- Veterinary Medicine: Applied as antibacterial drug for livestock and poultry.
- Biochemical Research: Used as selective bacteriostatic agent in microbial culture and laboratory research.
Safety & Storage Instructions
- Hazard Classification: Common allergen; may cause allergic reactions, skin and respiratory irritation. Harmful if excessive intake.
- Personal Protection: Wear dust mask, safety goggles and chemical resistant gloves. Avoid dust inhalation, skin contact and accidental ingestion.
- Storage Condition: Keep containers tightly sealed. Store in cool, dry, dark and well-ventilated area. Strictly moisture-proof, keep away from heat sources, acids and alkalis.
- Transportation: Classified as general pharmaceutical chemicals. Prevent package damage, dampness and high temperature during transit.
Quality & Spectral Data
- Purity (HPLC): ≥99.0%
- Loss on Drying: ≤1.0%
- Residue on Ignition: ≤0.2%
- Specific Rotation: +280° ~ +305°
- IR Spectrum: Characteristic absorption peaks conform to standard reference spectrum
