What Is Sulfaquinoxaline Sodium?

Sulfaquinoxaline Sodium is a broad-spectrum sulfonamide antimicrobial and veterinary drug. It is the water-soluble sodium salt of sulfaquinoxaline, primarily used to prevent and treat coccidiosis (a parasitic intestinal disease) and certain bacterial infections in livestock and poultry, such as cattle, sheep and chickens. Sulfaquinoxaline Sodium Powder is supplied as a veterinary raw material for formulation development and research applications.

Its sodium-salt form dissolves easily in water, making it suitable for drinking-water and solution-based veterinary applications requiring a water-soluble sulfonamide material.

What Is Sulfaguanidine API Used For?

Sulfaguanidine API is a sulfonamide antibacterial starting material targeting susceptible gram‑negative enteric pathogens. All finished products manufactured from this raw material must comply with local veterinary regulatory standards.

● Oral Soluble Powder Formulations: Core raw material for veterinary oral soluble powder against swine and poultry bacterial enteritis and bacillary dysentery.

● Veterinary Oral Tablet & Bolus Intermediates: Technical intermediate for solid oral veterinary dosage forms for intestinal infection control.

● Pharmaceutical R&D Intermediate: Raw material for sulfonamide‑based intestinal antibacterial formulation research.

● Custom formulation projects targeting gastrointestinal gram‑negative bacterial infections in livestock.

How Does Sulfaquinoxaline Sodium Work?

Sulfaquinoxaline Sodium is a sulfa drug that works by blocking folic acid creation in parasites and bacteria, which stops them from growing. It acts as a structural analogue of PABA (para-aminobenzoic acid), competing for the enzyme dihydropteroate synthase (DHPS) and tricking parasite cells so they cannot make vital food and nucleoproteins required for replication.

This mechanism makes Sulfaquinoxaline Sodium Powder a useful reference compound for veterinary antimicrobial and coccidiosis mechanism studies.

What Are the Applications of Sulfaquinoxaline Sodium?

Poultry Health: Used in research and formulation development for coccidiosis control (caused by Eimeria species), as well as studies involving acute fowl cholera (Pasteurella multocida) and fowl typhoid (Salmonella gallinarum) in chickens and turkeys.
Livestock Management: Evaluated for intestinal coccidiosis research in cattle, calves and sheep.
Antimicrobial Research: Used to study bacterial folate-pathway inhibition and DHPS-related mechanisms.
Combination Formulation Studies: Evaluated in combination with amprolium, ethopabate or other anticoccidial agents for synergistic research.
Water and Feed Formulation: Suitable for solubility, drinking-water formulation and process-development studies, as the sodium salt dissolves easily in animal drinking water or mixes evenly into feed.

What Is the Difference Between Sulfaquinoxaline and Sulfaquinoxaline Sodium?

Feature	Sulfaquinoxaline	Sulfaquinoxaline Sodium
CAS	967-80-6	547-32-0
Form	Base compound (free acid)	Sodium salt derivative
Solubility	Lower water solubility	Highly water-soluble
Typical Use	Often mixed into animal feed formulations	Commonly added to animal drinking water for rapid administration

How Does Sulfaquinoxaline Sodium Compare With Other Veterinary Sulfonamides?

Feature	Sulfaquinoxaline Sodium	Sulfadimidine Sodium	Sulfachlorpyridazine Sodium
CAS	967-80-6	1981-58-4	23282-55-5
Primary Focus	Antiprotozoal (Eimeria/coccidiosis) + antibacterial	Systemic bacterial infections	Veterinary antibacterial
Plasma Half-Life	Prolonged / extended	Short-acting	Short-acting
Distinctive Trait	Strong anticoccidial efficacy; Vitamin K inhibition at high doses	Broad antibacterial	Poultry coccidiosis use

How Is Sulfaquinoxaline Sodium Manufactured?

Sulfaquinoxaline Sodium is manufactured by first synthesizing the base compound sulfaquinoxaline from o-phenylenediamine and chloroacetic acid (or glyoxylic acid) to build the quinoxaline ring, followed by chlorination, condensation with p-aminobenzenesulfonamide, and finally treatment with sodium hydroxide to form the water-soluble sodium salt.

Raw Material QC → Quinoxaline Ring Synthesis → Chlorination → Sulfonamide Condensation → Purification → Sodium Salt Formation → Drying → Final QC → Packaging

HDM BIO controls key synthesis, purification and drying parameters to maintain consistent purity and batch quality.

What Quality Control Tests Are Performed for Sulfaquinoxaline Sodium?

Each batch undergoes multi-step quality control before release to ensure chemical purity, identity and potency.

Raw Material QC → In-Process Control → HPLC Assay → IR/UV Identity Verification → Acidity & Impurity Testing → Loss on Drying → Heavy Metals → Final Batch Release

Key evaluations include identification via infrared (IR) and ultraviolet (UV) absorption, HPLC active content assay, acidity titration, loss on drying, residue on ignition and heavy metal limits. Every commercial batch is supported by a batch-specific COA and relevant analytical documentation for incoming QC and supplier qualification.

What Factors Affect Sulfaquinoxaline Sodium Bulk Price?

Sulfaquinoxaline Sodium bulk pricing is driven by several key factors:

Raw Material & Intermediate Costs: Fluctuations in basic chemical precursors and upstream intermediates directly shift baseline manufacturing cost.
Livestock & Poultry Market Demand: Demand is tied to the scale of animal breeding and farming sectors.
Purity & Specifications: Standard veterinary grades differ from high-purity research grades for specialized formulations.
Regulatory & GMP Compliance: Manufacturing plants meeting stringent GMP or environmental standards incur higher operational costs.
