Tri-Sodium Citrate Dihydrate >99.90 % BP, USP, FG

What is Tri-Sodium Citrate Dihydrate? With the chemical formula Na₃C₆H₅O₇·2H₂O, and also sometimes shortened to Sodium Citrate, it is the sodium salt of citric acid and is commonly found as a colourless or white crystalline powder. The 99% purity grade is highly valued in both laboratory and industrial applications. This compound is used primarily as a buffering agent, preservative, and anticoagulant. It plays a significant role in pH regulation, particularly in medical solutions, and is frequently used in food and beverage formulations, as well as in laboratory diagnostics and treatments for metabolic conditions.

Consistent Quality: We source only the highest-purity Tri-Sodium Citrate Dihydrate (99%) to ensure consistent and reliable performance across a wide range of applications, meeting the standards of ACS (American Chemical Society), USP (United States Pharmacopeia), and Ph Eur (European Pharmacopoeia).

Shipped from Manchester, UK Facility: Sourced and packaged in non-toxic, chemical-resistant containers, ensuring reliable quality for our customers.

Frequent Uses

Buffering Agent
Widely used in laboratories to prepare buffer solutions. It is essential for maintaining pH stability in biochemical assays, DNA extractions, and protein purification processes. It is particularly useful in maintaining optimal conditions for enzymes and other biological systems.

Food and Beverage
As an acidulant and preservative. It helps regulate acidity in products such as soft drinks, processed cheeses, and jams, ensuring longer shelf life and enhancing flavour profiles.

Pharmaceuticals and Medical Applications
Used to stabilise active ingredients and adjust the pH in injectable formulations. It is also employed in medical treatments, particularly in the management of blood clotting disorders, as it functions as an anticoagulant by binding to calcium ions.

Anticoagulant in Blood Samples
In clinical laboratories, it is used as an anticoagulant in blood sample collection, preventing clotting during storage and analysis. It is frequently included in blood collection tubes for diagnostic purposes.

Biotechnology
Used for its buffering properties in the preparation of cell culture media, where it helps maintain pH levels and supports the growth of microorganisms and cells in vitro.

Cleaning and Decontamination
Due to its ability to bind metal ions, it is sometimes used in cleaning and decontamination procedures, especially for removing calcium and magnesium buildup from equipment and instruments in industrial and laboratory settings.
