Frequently Asked Questions
What is sodium citrate used for?
Sodium citrate (trisodium citrate, CAS 68-04-2) is the sodium salt of citric acid, used industrially as a buffering agent for pH control, as a sequestrant that binds metal ions, and as an emulsifying salt. It also serves as a builder and sequestrant in detergent formulations and as a complexing agent in electroplating baths.
Is sodium citrate just salt?
No. Sodium citrate is the trisodium salt of citric acid (C6H5Na3O7), chemically distinct from sodium chloride (table salt). It functions as a buffer and metal-ion sequestrant rather than a flavoring salt.
What is the formula for sodium citrate?
Trisodium citrate has the molecular formula C6H5Na3O7 (CAS 68-04-2). It is the fully neutralized sodium salt of citric acid.
What HS code is sodium citrate classified under?
Sodium citrate is typically classified under HS code 2918.15 (salts and esters of citric acid). Confirm the destination-country tariff line and request a CoA and SDS with your order.
What is the cost of bulk sodium citrate?
Bulk pricing depends on grade, packaging (bags, drums, totes), and volume. Request a bulk quote with your target quantity and grade requirements; we supply to manufacturers and blenders.
What is the REACH and TSCA regulatory status of Sodium Citrate (Trisodium Citrate)?
Sodium Citrate (Trisodium Citrate) (CAS 68-04-2) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 200-675-3).
