Synonymes : Cefotaxime sodium, 64485-93-4, Sodium cefotaxime, Cefotaxime sodium salt, CTX sodium, 7-[2-(2-Amino-4-thiazolyl)-2-methoxyiminoacetamido]cephalosporanic acid sodium salt
Bulk buyers of cefotaxime sodium are mostly sterile injectable manufacturers, veterinary formulators, and contract research organizations that need a dependable third-generation cephalosporin API for their own finished products. The demand is steady rather than seasonal, driven by hospital formularies and livestock health programs in regions where this spectrum still holds a clinical edge. What buyers ask for first is a clean assay profile, consistent particle size, and full traceability from the synthesis batch to the drum.
Cefotaxime sodium is the sodium salt of cefotaxime, a semisynthetic cephalosporin antibiotic. We supply it as a white to off-white crystalline powder, typically assayed at 97% or higher by HPLC, and packed under controlled conditions to protect it from moisture and light. Each batch is released against a specification that includes identity, assay, and water content, and we can provide a sample for your own laboratory qualification before you commit to a bulk order.
Because the molecule is sensitive to heat and humidity, storage and handling matter as much as the certificate of analysis. We ship in tightly sealed containers with desiccant where needed, and we recommend storing the material below 25°C in a dry place away from direct sunlight. If your process requires a specific particle size distribution or a sterile grade, let us know at the inquiry stage so we can confirm availability against your timeline.
We stock cefotaxime sodium as a non-sterile, injectable-grade powder. The standard specification is built around HPLC assay, identity by IR, and water content, and every batch is tested for solubility and clarity of solution before release. For customers who need a sterile product, we can discuss terminal sterilization or aseptic processing options, but those are handled on a case-by-case basis and may affect lead time.
The material is supplied as a fine crystalline powder that flows well in hopper-based filling lines. It dissolves readily in water, which makes it suitable for lyophilized vials and sterile suspensions. We do not stock pre-formulated blends or liquid concentrates; the product is shipped as a raw API only.
Most of this material goes into sterile injectable formulations—powder for injection in vials, and lyophilized cakes for reconstitution. Formulators also use it in veterinary injectables for cattle and swine, and in some oral suspensions for companion animals where a broad-spectrum cephalosporin is needed. In these systems, cefotaxime sodium acts as the active pharmaceutical ingredient, and the formulation challenge is usually about pH adjustment and isotonicity rather than the API itself.
Because the powder is hygroscopic, formulators typically handle it in low-humidity environments and use nitrogen blanketing during filling. It is compatible with common excipients such as sodium chloride and dextrose, but stability studies should be run for each specific formulation since degradation can occur at higher pH. For R&D labs, we can supply small quantities for feasibility work before scale-up.
