Applications
- Food industry — acidity regulator, chelating agent and stabilizer for beverages, dairy products and canned goods.
- Pharmaceutical industry — in vitro anticoagulant and pharmaceutical pH buffer.
- Personal care — chelating agent and pH regulator for cosmetic and personal care formulations.
- Industrial applications — concrete retarder, electroplating complexing agent and raw material for eco-friendly cleaning agents.
Trisodium Citrate Dihydrate vs Anhydrous Sodium Citrate
The dihydrate contains two molecules of water of crystallization and has the formula Na₃C₆H₅O₇·2H₂O; anhydrous sodium citrate contains no water of crystallization. Because their molecular weights and active-content basis differ, they should not be substituted on an equal-weight basis without recalculating the formulation. Confirm the required form, assay basis and process conditions before purchase.
Grade and Order Selection
| Application | Confirm before ordering | Order review |
|---|---|---|
| Food and beverage | Target market, required specification, impurity limits and particle form | Confirm the offered grade and destination requirements before purchase. |
| Pharmaceutical or laboratory | Required compendial or application-specific standard and intended use | No pharmaceutical suitability is assumed without specification review. |
| Personal care and industrial | Buffering or chelating need, particle form, packaging and process conditions | Confirm suitability against the buyer's formulation and acceptance criteria. |
Packaging, Storage & Compliance
Packaging can be arranged according to order requirements and destination-market regulations. Store in a dry, ventilated area away from moisture and incompatible materials. For food, pharmaceutical or personal care use, confirm the required grade, destination-market regulations and documentation before order confirmation.

FAQ
Is trisodium citrate dihydrate the same as sodium citrate dihydrate?
Yes. “Sodium citrate dihydrate” commonly refers to trisodium citrate dihydrate, CAS 6132-04-3. Buyers should still confirm the full chemical name, hydration form and specification on the order.
What is the difference between trisodium citrate dihydrate and anhydrous sodium citrate?
The dihydrate contains two waters of crystallization, while the anhydrous form does not. Their molecular weights and concentration basis differ, so formulation quantities may need to be recalculated.
What is Trisodium Citrate Dihydrate used for?
Depending on the required grade and application, it is used as an acidity regulator, chelating agent, stabilizer, pH buffer, concrete retarder and electroplating complexing agent.
What HS code and documents are required?
Customs classification can depend on the destination country and declared use. Confirm the HS code with the importer or customs broker. Provide the destination and application so YuXing can review the order requirements and privately confirm the available supporting documents.
Are TDS, SDS and COA documents publicly available?
No. Product and batch documents are not currently offered as public downloads. Their availability can be reviewed privately after the buyer provides the application, required grade, quantity and destination.
Is YuXing a trisodium citrate manufacturer or supplier?
YuXing is an export-oriented chemical supplier that coordinates product matching, sourcing, packaging and shipment support. The proposed manufacturing source and specification are confirmed for the individual inquiry; this page does not claim that every offered batch is manufactured by YuXing.
