Product Name: High Quality sulfamethazine cas 57-68-1 With Best Price. Sulfamethazine is an organic compound with the chemical formula C₁₂H₁₄N₄O₂S. It is a white or yellowish - white crystalline powder. The CAS number 57 - 68 - 1 uniquely identifies this chemical substance in the chemical industry. Its molecular weight is approximately 278.33 g/mol.
The melting point of sulfamethazine is around 197 - 201 °C. It is slightly soluble in water, soluble in acetone, and soluble in dilute acids and alkalis. High - quality sulfamethazine should have a high degree of purity, usually above 98%, which ensures its effectiveness in various applications.
Sulfamethazine is widely used in the veterinary field. It is an important sulfonamide antibiotic. It can be used to prevent and treat a variety of bacterial infections in livestock and poultry. For example, it is effective against respiratory tract infections, intestinal infections, and urinary tract infections in pigs, cattle, and chickens. By inhibiting the growth and reproduction of bacteria, it helps to improve the health of animals and reduce the risk of disease outbreaks in large - scale animal farming.
In addition to its veterinary uses, sulfamethazine also has certain applications in the laboratory. It can be used as a reference standard in chemical analysis and microbiological research. Scientists can use it to study the antibacterial mechanisms of sulfonamide drugs and develop new antibacterial agents.
In veterinary applications, the usage of sulfamethazine depends on the type of animal, the severity of the disease, and the route of administration. For oral administration in pigs, the common dosage is usually 20 - 50 mg per kilogram of body weight per day, divided into two or three doses. For cattle, the dosage may be adjusted according to their body size and the specific condition, generally ranging from 10 - 30 mg per kilogram of body weight per day.
When using sulfamethazine, it should be dissolved in an appropriate solvent first if necessary. For example, it can be dissolved in a dilute acid solution before mixing with feed or drinking water. It is important to ensure thorough mixing to ensure that each animal gets the correct dose. In laboratory use, strict operating procedures should be followed according to specific experimental requirements, such as accurate weighing and careful preparation of solutions.
Case 1: A pig farm in a rural area was facing a severe outbreak of respiratory tract infections. The pigs showed symptoms such as coughing, sneezing, and reduced appetite. The veterinarian recommended using sulfamethazine. After calculating the appropriate dosage according to the pigs' body weight, the drug was mixed into the feed. Within a week, the symptoms of most pigs were significantly alleviated. After two weeks of continuous use, the infection was basically under control, and the pigs' health and growth rate improved.
Case 2: In a laboratory research project on antibacterial mechanisms, sulfamethazine was used as a reference standard. The researchers compared the antibacterial activity of sulfamethazine with a new synthetic antibacterial agent against a specific type of bacteria. By measuring the minimum inhibitory concentration (MIC) of the two substances, they found that although the new agent had a certain antibacterial effect, sulfamethazine still showed better performance in inhibiting the growth of the bacteria under the same experimental conditions.
