Product Name: Zinc Pivalate
Chemical Formula: C10H18O4Zn
Synonyms: Zinc trimethylacetic acid, zinc neopentanoate
Physical Appearance: White crystalline powder, mild odor uncommon
Primary Uses: Usually finds application in specialty chemical synthesis or as a catalyst in organic reactions, less frequently encountered compared to more common zinc salts
Main Risks: Irritation to eyes, skin, or respiratory tract. Prolonged or repeated exposure can cause minor health symptoms in sensitive individuals
Hazard Class: Classified as a mild irritant, does not carry the severe risks associated with heavy metals
Signal Words: Caution, as accidental exposure, especially to dust, can provoke discomfort
Routes of Exposure: Most concern centers around inhalation of powder during handling or accidental skin contact. Large scale manufacturing processes without dust control increase these risks
Main Ingredient: Zinc pivalate
CAS Number: 15716-65-5
Impurities: Potential trace amounts of unreacted pivalic acid or other metallic residues. High-purity material should record minimal contaminants, but purity levels can vary across suppliers
Eye Contact: Prompt washing with water reduces irritation. Seek medical advice if discomfort persists, especially for those with a prior history of eye sensitivity
Skin Contact: Wash off with soap and water. Most reactions resolve quickly, but rash-prone individuals might notice mild irritation
Inhalation: Move to fresh air; shallow breathing or coughing should stop once away from the source
Ingestion: Rare in lab settings, but accidental swallowing by children or untrained handlers can occur. Rinsing the mouth and monitoring for symptoms suits most minor cases
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemicals, or carbon dioxide, depending on what is safe for the surrounding area
Thermal Hazards: Under intense heat, organic fragments may break down and release potentially harmful fumes such as carbon oxides or zinc oxide particles
Protective Gear: Firefighters usually prefer full protective clothing and breathing apparatus, especially if smoke develops from storage or manufacturing mishaps
Explosion Potential: Not considered an explosive risk under normal handling conditions
Personal Protection: Dust mask, chemical resistant gloves, and goggles
Spill Response: Sweep up without raising dust. Wetting the powder slightly before sweeping controls airborne exposure
Environmental Precaution: Prevent runoff into water bodies. Even mild zinc contamination can upset aquatic ecosystems, so even small spills in sensitive locations demand care
Handling Advice: Use well-ventilated spaces or local extraction to keep powder away from faces. Personal recollection points to the importance of labeled containers and reminders to wash hands after use, even when gloves are worn
Storage Conditions: Cool, dry place in tightly closed containers. Humidity or heat speeds up degradation and reduces material stability, which has caused headaches in more humid climates
Incompatibles: Store away from acids, oxidizing agents, and active metal powders, which may react with organic zinc compounds in unpredictable ways
Engineering Controls: Fume hoods and good ventilation cut risks to almost nothing in most lab or industrial settings
Personal Protection: Safety glasses, laboratory coats, impervious gloves, and dust masks form the minimum PPE. Some sites prefer powered respirators where powders are weighed out for extended periods
Permissible Exposure: Not established for zinc pivalate, but general dust limits for particulates apply. Operators in my experience appreciate regular air monitoring to avoid surprises
Appearance: White, crystalline powder
Molecular Weight: 267.64 g/mol
Solubility: Low in water but higher in organic solvents like alcohols
Melting Point: Around 125-130 °C, but can differ among producers
Odor: Practically odorless, hard to detect unless heated
Density: Information limited, but heavier than most organic powders
Chemical Stability: Stable under standard laboratory or warehouse conditions
Conditions to Avoid: Moisture, strong acids or oxidizing agents
Hazardous Decomposition Products: Zinc oxide dust and low concentrations of carbon oxides during combustion
Reactivity: Not prone to hazardous polymerization or spontaneous breakdown under normal use
Main Exposure Symptoms: Irritation to respiratory tract if dust is inhaled, and to eyes or skin with direct contact
Chronic Effects: Not strongly linked to systemic toxicity in available literature, though prolonged exposure to zinc salts has been linked to gastrointestinal upset or interference with copper metabolism
Acute Oral LD50: Not clearly documented for zinc pivalate; data from zinc compounds show relatively low toxicity by ingestion
Vulnerable Groups: Children and those with preexisting allergies might be more likely to see mild mucous membrane sensitivity
Environmental Fate: Zinc compounds build up more easily in soil and water compared to many organic chemicals
Aquatic Toxicity: Like other zinc salts, zinc pivalate can harm aquatic invertebrates and fish if released even in moderate quantity
Persistence: Moderate; organic portion breaks down with time, but zinc ions linger
Bioaccumulation: Zinc may accumulate in water systems, impacting food chains under chronic exposure scenarios
Waste Handling: Seal powder or contaminated materials in containers for hazardous waste pickup. Direct disposal to drain or landfill creates risks for water systems and wildlife
Incineration: Only in authorized facilities that handle chemical wastes with scrubbers for metal-laden exhaust
Recycling: Uncommon for this chemical, due to the specialized end uses and small volumes typically produced
UN Number: Not listed as a hazardous material under many transport regulations
Transport Category: Ordinary solid substance, shipped in sealed bags or drums
Risks in Transit: Main concern centers on ruptured sacks or crushed drums spilling powder, particularly during rough handling in bulk quantities
Packing Group: Not assigned, but routine chemical hygiene for powders applies based on observed industry practice
Safety Regulation: Not recognized as a major hazardous chemical in most workplaces, but worker protection acts require assessment under general chemical safety legislation
Labeling: Requirements usually call for hazard pictograms indicating irritation, and advice to avoid dust exposure
Community Right-to-Know: Employees in production or lab settings value transparent information about all materials on site; updated MSDS sheets posted in shared spaces remain important
National Registers: Zinc pivalate does not commonly appear on restrictive or controlled chemical lists, though concentrations of zinc in waste and emissions face scrutiny
