Description
Metatartaric Acid - 500g
Other Names: Metavin, polymerized tartaric acid
CAS Number: 35841-73-3
Sum Formula: (C₄H₆O₆)ₙ
Molar Mass: Variable (polymeric form)
Appearance: White to off-white powder
Metatartaric acid is a polymerized form of tartaric acid, created through partial dehydration, resulting in ester bonds between molecules. It is primarily used in the chemical industry for its chelating and stabilizing properties in various technical processes and formulations. Its structure makes it less soluble than tartaric acid, with altered acid-base behavior useful in specialized applications.
Applications
Chemical Industry: Used as a processing aid and acidity regulator in chemical formulations. Functions as a chelating agent for metal ions and may serve in systems requiring scale inhibition or ion sequestration.
Technical Uses: Applied in coatings, treatment solutions, and process liquids where reduced crystallization or tartaric precipitation is needed.
Safety
Signal Word: Danger
Hazard Statements:
H318: Causes serious eye damage.
Precautionary Statements:
P280: Wear eye protection/face protection.
P305 + P351 + P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
First Aid Measures
Eye Contact: Immediately rinse eyes with plenty of water for several minutes. Remove contact lenses if present and easy to do. Seek medical attention immediately.
Skin Contact: Wash affected area with water. Remove contaminated clothing. Seek medical attention if irritation persists.
Inhalation: Move to fresh air. Seek medical attention if symptoms such as coughing or shortness of breath occur.
Ingestion: Rinse mouth with water. Do not induce vomiting. Contact a doctor if feeling unwell.
Handling and Storage
Storage Conditions: Store in a dry, cool, and well-ventilated area. Keep container tightly closed and protected from moisture and incompatible substances (e.g., strong oxidizers).
Handling Precautions: Avoid formation of dust. Use appropriate personal protective equipment, especially for eye and skin protection.
