Sodium Pyrophosphate CAS 7758-16-9

1. Sodium pyrophosphate is used as a buffering agent, emulsifier, dispersing agent, and thickening agent in industrial and laboratory applications, as well as a nutritional supplement and food additive in products such as chicken nuggets, crab meat, and canned tuna .
2. Sodium pyrophosphate CAS 7758-16-9 functions as a chelating agent and water softener, binding metal ions such as calcium and magnesium to prevent precipitation and improve detergent performance, and is also used as a tartar control agent in toothpaste and dental floss .
3. In biochemical research, sodium pyrophosphate is employed as a phosphatase inhibitor (serine/threonine phosphatase irreversible inhibitor) and as a component in buffer systems for stabilizing proteins and preventing aggregation .
4. Sodium pyrophosphate is utilized as an inorganic additive in redox flow batteries to improve stability and electrochemical performance, and serves as an electroactive media for surface exfoliation in materials science applications .

1. Sodium pyrophosphate must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at ambient temperatures, as the anhydrous form is hygroscopic and should be stored under nitrogen .
2. Sodium pyrophosphate CAS 7758-16-9 is classified with GHS hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), with signal word "Warning" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Keep Sodium pyrophosphate CAS 7758-16-9 away from incompatible materials such as strong oxidizing agents and strong acids to prevent decomposition; sodium pyrophosphate is soluble in water (≥30 mg/mL) but insoluble in alcohol and ammonia .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when sodium pyrophosphate is released .
2. Collect Sodium pyrophosphate CAS 7758-16-9 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations; the substance has WGK Germany 1 classification (low water hazard potential) .

1. Sodium pyrophosphate is not classified as highly flammable (flash point not applicable) but is classified as a combustible solid (Storage Class 11) and may decompose under fire conditions .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as Sodium pyrophosphate CAS 7758-16-9 may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning sodium pyrophosphate due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
