Sulfadimethoxine Sodium (English name Sulfadimethoxypyrimidine sodium salt)(link:https://www.bloomtechz.com/synthetic-chemical/api-researching-only/sulfadimethoxine-sodium-cas-1037-50-9.html) is also known as Sulfadimethoxine sodium (Sulfadimethoxine sodium), Sulfa-6-methoxine sodium (Daimeton sodium). It is white or off-white powder at normal temperature, soluble in water and dilute inorganic acid solution. It is easy to deteriorate when exposed to light, and the color gradient becomes darker. Sulfadimethoxine sodium is a sulfonamide drug, mainly used for sensitive bacterial infections, but also for infections such as Toxoplasma gondii and leukocytosia in chickens. Sulfadimethoxine sodium is a sulfonamide drug, which not only has broad-spectrum antibacterial effects, but also has significant anti-coccidian and anti-toxoplasma effects. It is mainly used for the infection of sensitive bacteria, for the prevention and treatment of chicken and rabbit coccidiosis, and also for the prevention and treatment of chicken infectious rhinitis, fowl cholera, leukocytozoon carinii disease, pig toxoplasmosis, etc. The effect of sulfadimethoxine sodium on chicken coccidia is the same as that of sulfaquinoxaline, that is, it is more effective on chicken small intestinal coccidia than cecal coccidia.
1. Treatment of intestinal infection: Sulfadimethoxine Sodium can be used to treat intestinal infection in rabbits, such as bacterial diarrhea caused by Escherichia coli and Salmonella. It inhibits the synthesis of dihydrofolate by bacteria and interferes with the metabolic process of bacteria to achieve antibacterial effects.
2. Ear infection treatment: Rabbits are often prone to ear infections, such as otitis media or external ear canal infections caused by fungi or bacteria. Sulfadimethoxine Sodium can be used as a topical or systemic treatment to control the spread of infection and reduce symptoms of inflammation.
3. Treatment of urinary tract infection: Sulfadimethoxine Sodium can be used to treat urinary tract infection in rabbits, such as cystitis, urethritis, etc. It can reduce infection symptoms and help restore normal function of the urinary tract by inhibiting the growth and reproduction of bacteria.
4. Pneumonia Treatment: Rabbits may develop bacterial pneumonia, especially in tight housing environments. Sulfadimethoxine Sodium can treat pneumonia by inhibiting the growth of bacteria in the lungs and relieve respiratory symptoms.
5. Skin infection treatment: Rabbit's skin is easily affected by trauma or fungal and bacterial infection. Sulfadimethoxine Sodium is used in the treatment of skin infections such as cellulitis, boils, etc. It inhibits the growth and spread of pathogens by applying it directly to infected skin areas.
6. Treatment of infectious diseases: Rabbits may suffer from some infectious diseases, such as coccidiosis and staghorn related diseases. Sulfadimethoxine Sodium can be used to prevent and treat these diseases, and control the spread and development of diseases by interfering with the metabolic pathways of pathogens.
7. Treat porcine toxoplasmosis. Toxoplasmosis is a zoonotic disease. Pigs will have high fever, breathing, fever, and nervous system symptoms after infection. Pigs show depression and loss of appetite. After diagnosis, use compound sulfonamide M-methoxine sodium, combined with other antipyretic and anti-inflammatory drugs, can be cured within a few days.
8. Treatment of coccidiosis and erythroderma. Coccidia and erythroderma are easy to infect young piglets. After infection, sulfamethoxine sodium and doxycycline can be mixed for intramuscular injection, and the therapeutic effect is obvious. In order to prevent piglets from being infected with coccidia, sulfamethoxine sodium is mixed with sows for five consecutive days, which can prevent coccidia very well.

9. For the treatment of atrophic rhinitis, Sulfamethoxine sodium is the first recommended drug after pigs suffer from rhinitis. It has a remarkable effect when used together with other drugs for seven days.
10. Pig meningitis, after pigs get meningitis, choose penicillin drugs combined with sulfamethoxine sodium, dexamethasone, and glucose for treatment, which can improve the cure rate.
Sulfadimethoxine Sodium is a pharmaceutical compound that belongs to the sulfa class of antibacterial agents. Its molecular structure contains a sulfonamide group and a dimethoxypyrimidine ring. The following are the characteristics of its molecular structure:

1. Sulfonamide moiety:
- The molecule of Sulfadimethoxine Sodium contains a sulfonyl group, which is composed of sulfonyl group and amino group.
- The benzenesulfonyl group is a group with a sulfonyl (SO2) group attached to an aromatic ring, which imparts antibacterial activity to the compound.
- Amino groups contain a nitrogen atom that can form hydrogen bonds or participate in other reactions.
2. Dimethoxy Pyrimidine ring:
- The molecule of Sulfadimethoxine Sodium contains a dimethoxypyrimidine ring, which is composed of a pyrimidine ring and two methoxy groups.
- The pyrimidine ring is a six-membered heterocyclic ring consisting of four carbon atoms and two nitrogen atoms.
- Methoxy is a group of one methyl group and one oxygen atom that imparts certain solubility and chemical reactivity to the molecule.
3. Functional group:
- The sulfonyl group and dimethoxypyrimidine ring in Sulfadimethoxine Sodium are the main functional groups of the compound.
- The sulfonamide group endows the molecule with antibacterial activity, inhibiting the growth and reproduction of bacteria by interfering with their metabolic pathways.
- The dimethoxypyrimidine ring affects the pharmacological activity and pharmacokinetic properties of the molecule.
4. Sodium salt form:
- Sulfadimethoxine Sodium is the sodium salt form of Sulfadimethoxine, which forms a stable salt by combining with sodium ions.
- Sodium ions increase the water solubility of the molecule and provide better stability and workability in pharmaceutical formulations.
