[Chemical Properties]

Acetyltriethyl citrate occurs as a clear, odorless, practically colorless oily liquid.
[Uses]

ATEC is produced by the reaction of citric acid triethyl ester with acetic acid anhydride. It is used as a solvent plasticizer for cellulose nitrate and cellulose acetate.
[Production Methods]

Acetyltriethyl citrate is prepared by the esterification of citric acid with ethanol followed by acylation with acetic anhydride.
[General Description]

Certified pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Triethyl 2-acetylcitrate is widely used in hydrophilic adhesives for medications and in biodegradable composition for papermaking and nonwoven production.
[Pharmaceutical Applications]

Acetyltriethyl citrate is used to plasticize polymers in formulated pharmaceutical coatings. The coating applications include capsules, tablets, beads and granules for taste masking, immediate release, sustained-release and enteric formulations. It is also used in diffusion-controlled release drug delivery systems.
[Safety]

Acetyltriethyl citrate is used in oral pharmaceutical formulations and is generally regarded as a nontoxic and nonirritating material. However, ingestion of large quantities may be harmful.
LD50 (cat, oral): 8.5 g/kg
LD50 (mouse, IP): 1.15 g/kg
LD50 (rat, oral): 7 g/kg
[storage]

Acetyltriethyl citrate should be stored in dry, closed containers at temperatures not exceeding 388℃. When stored in accordance with these conditions, acetyltriethyl citrate is a stable product.
[Incompatibilities]

Acetyltriethyl citrate is incompatible with strong alkalis and oxidizing materials.
[Regulatory Status]

Approved in the USA for direct food contact in food films.
