Supplier Qualification Packet
One zipped download containing the TDS, SDS, latest lot COA (when available), and a fresh Letter of Continuing Guaranty for Trisodium Phosphate Dodecahydrate - ACS Reagent Grade. Every file included is SHA-256 hashed and listed in a manifest your QA team can audit.
Application Guidance
Trisodium Phosphate Dodecahydrate - ACS Reagent Grade (ACS Reagent) is supplied across multiple grades. Grade selection drives the appropriate end-use — food/pharma, technical, or specialty.
- Brine production and de-icing
- Concrete and construction (set acceleration, dust control)
- Food and beverage applications (food-grade only)
- Oilfield and drilling fluid additive
- Chemical manufacturing precursor
Often hygroscopic — store in sealed containers, control humidity. Hydrate form (anhydrous vs di/hexa-hydrate) affects mass-equivalent dosing.
Storage & Handling
- Recommended Storage
- Cool, dry area in sealed containers. Many salts are hygroscopic — protect from atmospheric moisture, which can cause caking, hydrate formation, or reduced flow.
- Handling Precautions
- Standard chemical PPE — dust mask and goggles for handling of fine grades. Avoid generating airborne dust.
- Incompatibilities
- Specific incompatibilities depend on the salt — consult the SDS. Many salts react with strong acids to release gases.
- Shelf Life
- 24 months from date of manufacture in sealed, original packaging
