Cell culture reagents (high-demand scenarios) :
As an essential additive for cell culture media, its concentration is usually 1-10mM. Its core functions are: ① To provide a rapid energy source (more easily absorbed and utilized by cells than glucose), supporting cell proliferation and metabolism; ② Eliminate reactive oxygen species (ROS) generated during cell culture, reduce the damage to cells caused by oxidative stress, and increase cell survival rate (especially suitable for the culture of sensitive cells such as stem cells and hybridoma cells); ③ Stabilize the pH value of the culture medium and improve the microenvironment for cell growth.
Applicable scenarios: Biopharmaceutical research and development (antibody drugs, vaccine production), cell therapy, in vitro diagnostics (IVD), basic research laboratories. It is an essential consumable for global biological laboratories.
Raw materials for pharmaceuticals and health products:
Pharmaceutical excipients: Sodium pyruvate powder is used to prepare oral or injectable preparations (such as energy supplements and antioxidant drugs), assisting in the treatment of fatigue syndrome, metabolic disorders and other diseases. It has good biocompatibility and a human absorption rate of over 95%.
Health supplement additives: As “energy enhancers” and “antioxidants” added to sports nutrition supplements and anti-aging health products, they can quickly replenish energy and reduce free radical damage, which is in line with the trend of “natural and healthy” products in Europe and America.
Food additives
Acidity regulator: Pyruvic acid sodium salt is used in beverages, pastries, dairy products, etc., to adjust the pH value of the products and improve the taste and stability;
Nutritional fortifier Sodium Pyruvate 113-24-6, as an α -keto acid nutrient, supplements the intermediates required for human metabolism and is suitable for special medical purpose formula foods (such as foods specifically for diabetic patients) and infant formula foods (which must comply with GB 25596 and EU EC 178/2002 standards).
Preservatives: By taking advantage of their weak acidity and antioxidant properties, they can extend the shelf life of food (such as meat products and baked goods) and replace some chemical preservatives.
Cosmetic raw materials
Antioxidant: Sodium Pyruvate 113-24-6 is added to products such as face creams, essences, and masks to eliminate free radicals on the skin surface, delay skin aging, and improve dullness.
Moisturizing and repairing agent: Promoting the metabolism of skin cells and enhancing the skin barrier function, sodium pyruvate is suitable for sensitive skin and anti-aging skin care products (the addition amount is usually 0.5%-2%), which conforms to the research and development trend of “mild and efficient” in cosmetics.
Industrial catalysis: Sodium pyruvate, as an organic synthesis intermediate, is used in the synthesis of fine chemical products such as pyruvate esters, amino acids, and heterocyclic compounds. It features high catalytic efficiency and mild reaction conditions (normal temperature and pressure are sufficient).
Feed additive: Sodium pyruvate is used in livestock, poultry and aquatic feed to enhance the energy metabolism efficiency of animals, boost immunity and improve growth performance (such as increasing the weight gain of broilers and the egg production rate of laying hens). It must comply with feed grade standards (such as GB 13078).
Analytical reagent: As a standard for chromatographic analysis (HPLC), sodium pyruvate is used for the content detection of pyruvate substances in food and medicine, with a purity requirement of ≥99.5% (analytical grade).

Tranexamic Acid with CAS 1197-18-8 is a synthetic derivative of lysine. It is a commonly used hemostatic agent in clinical practice. It plays a hemostatic effect by inhibiting the dissolution of fibrin. Trantranic acid can strongly adsorb Lysine-binding sites of fibrinogen affinity sites on plasminase and plasminogen, and inhibit the binding of plasminogen and fibrin, and thus strongly inhibit the decomposition of fibrin caused by plasminogen. In addition, the antifibrinolytic effect of tranatemic acid was more obvious in the presence of antifibrinolytic enzymes such as macroglobulin in serum

1-Acetyl-2-phenylhydrazine is an amide and an amine. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Polycaprolactone (PCL), CAS 24980-41-4, is a biodegradable, semi-crystalline polyester used in tissue engineering and drug delivery research. Due to its long aliphatic chain, PCL degrades significantly more slowly than other common biodegradable polymers, such as polylactic acid. PCL’s low melting point (55-60°C) makes it well-suited for thermal processing, making it a promising material for applications such as 3D printing, disposable food packaging, and medical sheeting.
For customers looking for polycaprolactone buy options, we provide polycaprolactone pellets for sale, available in bulk supply with competitive polycaprolactone pellets price.
