Potential Exposure
Ancymidol is a plant growth regulator
registered for treating container-grown herbaceous plants,
ornamental woody shrubs, and bedding plants grown in
greenhouses and other plant bedding areas for primarily
commercial production. Growth regulator used on plants
such as chrysanthemums, certain lilies, and poinsettias
effects produced by ancymidol are the result of inhibition
of gibberellin biosynthesis. It produces a more compact
growth form by suppressing elongation.
First aid
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a oneway
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running
water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation, ingestion
or skin contact) to substance may be delayed. Ensure that
medical personnel are aware of the material(s) involved
and take precautions to protect themselves. Medical observation
is recommended for 24 to 48 hours after breathing
overexposure, as pulmonary edema may be delayed.
As first aid for pulmonary edema, a doctor or authorized
paramedic may consider administering a drug or other
inhalation therapy.
Incompatibilities
Dust may form explosive mixture with
air. Ancymidol may react vigorously with oxidizing agents.
Mixtures with concentrated hydrogen peroxide or strong
mineral acids (e.g., nitric, sulfuric, perchloric) may cause
explosions. Mixtures with hypochlorous acid, lead perchlorate,
chlorine, bleaches, including sodium hypochlorite;
mixed water/carbon tetrachloride solution; trichloroisocyanuric
acid form methyl hypochlorite, which can be explosive,
especially when exposed to sunlight or heat. May
react with metallic aluminum at high temperature. Flow or
agitation of substance may generate electrostatic charges
due to low conductivity; ground all equipment containing
this material. May attacks some plastics, rubber, and
coatings.
Chemical Properties
Ancymidol is a white to buff colored crystalline
or granular solid. Slightly aromatic odor.
Waste Disposal
Dispose of contents and container
to an approved waste disposal plant. All federal, state,
and local environmental regulations must be observed.

Definition
ChEBI: A tertiary alcohol that is methanol in which the hydrogens attached to the carbon are replaced by cyclopropyl, p-methoxyphenyl and pyrimidin-5-yl groups. By inhibiting gibberellin biosynthesis, ancymidol reduces plant growth, resulting in redu
ed internode elongation and thus more compact plants. It is used in the commercial production of a wide variety of container-grown bedding and foliage plants, including chrysanthemums, Easter lilies and poinsettias.
General Description
Ancymidol, a-cyclopropyl-a-(4-methoxyphenyl)-5-pyrimidinemethanol (EL-53 1), a plant growth retardant is a synthetic pyrimidine analogue. It is also a weak fungitoxic.
Biochem/physiol Actions
Ancymidol is a pyrimidine-class plant cell endocrine disruptor plant growth regulator that interferes with gibberellin and cellulose biosynthesis.
