Overview
Hetacillin is a semi-synthetic penicillin antibiotic derived from ampicillin. It acts as a prodrug, converting to ampicillin in vivo, and is primarily used in veterinary applications due to its stability and efficacy against bacterial infections in animals. Developed to address the limitations of ampicillin, hetacillin offers improved bioavailability and resistance to gastric acid, making it suitable for oral administration in livestock. Its broad-spectrum activity targets pathogens like Escherichia coli, Salmonella, and Staphylococcus aureus.
Physical and Chemical Properties
Hetacillin appears as a white crystalline powder with a molecular weight of 389.47 g/mol. It is soluble in water and slightly soluble in ethanol, with a melting point around 190-195°C (with decomposition). The compound’s stability in acidic conditions distinguishes it from ampicillin, allowing for oral dosing. Its molecular structure includes a beta-lactam ring, critical for its antibacterial activity, which inhibits bacterial cell wall synthesis.
Main Applications
In veterinary medicine, hetacillin is widely used to treat respiratory, urinary, and gastrointestinal infections in cattle, swine, and poultry. It is administered via feed or water due to its palatability and solubility. The drug is also employed in aquaculture to control bacterial diseases in fish. Its broad-spectrum efficacy and cost-effectiveness make it a staple in livestock health management, though regional regulations may restrict its use to prevent antibiotic resistance.
Safety and Storage
Hetacillin should be stored in airtight containers at 2-8°C to prevent degradation. Exposure to moisture or light can reduce potency, requiring desiccants and opaque packaging. Safety precautions include wearing gloves and masks during handling to avoid skin contact or inhalation. Overuse can lead to antibiotic-resistant bacteria, so adherence to prescribed veterinary dosages is critical. Disposal must comply with local environmental guidelines.
B2B Procurement Guide
Bulk buyers should prioritize suppliers with Good Manufacturing Practice (GMP) certification and batch-specific Certificates of Analysis (CoA). Key specifications include purity (≥98%) and low endotoxin levels. Procurement contracts should account for lead times and cold-chain logistics, as stability is temperature-sensitive. Spot prices fluctuate based on raw material costs; long-term agreements may offer cost advantages. Verify regulatory compliance for target markets (e.g., FDA, EMA).
