3-Chloropivaloyl chloride (also known as 3-chloro-2, 2-dimethylpropionyl chloride) is a vital acylation reagent and isoxazolone cyclization reagent, is widely used in the organic synthesis industry, is used primarily as a medical intermediate and a pesticide intermediate at present, and is used as a synthetic raw material of a rubber additive and a photographic photosensitive material.
Verwenden
3-Chloropivaloyl Chloride is useful in the synthesis of compounds with antimicrobial and antioxidant activities.
Combustible material: may burn but does not ignite readily. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas (sewers, basements, tanks, etc.). Vapors may travel to source of ignition and flash back. Corrosives in contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. (ERG, 2024)

Gesundheitsgefahren
Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]:TOXIC and/or CORROSIVEinhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. Reaction with water or moist air may release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental contamination.

Highly flammable. Slightly soluble in water and less dense than water. Hence floats on water. Reacts with water to form hydrochloric acid (hydrogen chloride).
Brandbekämpfung
Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]:Note: Most foams will react with the material and release corrosive/toxic gases. CAUTION: For Acetyl bromide (UN1716), use CO2 or dry chemical only.SMALL FIRE: CO2, dry chemical, dry sand, alcohol-resistant foam.LARGE FIRE: Water spray, fog or alcohol-resistant foam. FOR CHLOROSILANES, DO NOT USE WATERuse alcohol-resistant foam. If it can be done safely, move undamaged containers away from the area around the fire. Avoid aiming straight or solid streams directly onto the product.FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. (ERG, 2024)

Erste Hilfe
Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]:Refer to the "General First Aid" section. Specific First Aid: For corrosives, in case of contact, immediately flush skin or eyes with running water for at least 30 minutes. Additional flushing may be required. Removal of solidified molten material from skin requires medical assistance. (ERG, 2024)General First Aid:· Call 911 or emergency medical service.· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.· Move victim to fresh air if it can be done safely.· Administer oxygen if breathing is difficult.· If victim is not breathing:-- DO NOT perform mouth-to-mouth resuscitationthe victim may have ingested or inhaled the substance.-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).-- If no pulse detected or no respiratory medical device available, provide continuous compressions.
