brown at 187℃. | [Definition]
ChEBI: A macrolide that is 13,19-didehydrosenecionan bearing two additional hydroxy substituents at positions 12 and 18 as well as two additional oxo groups at positions 11 and 16. | [General Description]
Colorless to off-white crystalline solid. Starts turning brown at approximately 329°F; is blackish-brown at melting point. | [Air & Water Reactions]
Exposure to light and air can cause gradual oxidation. Insoluble in water. | [Reactivity Profile]
riddelline reacts readily with oxidizing agents (slowly with atmospheric oxygen). On contact with bases, hydrolysis will probably occur . | [Fire Hazard]
Flash point data for riddelline are not available; however, riddelline is probably combustible. | [Potential Exposure]
Riddelline is a natural alkaloid product
used a laboratory chemical and reference standard. | [First aid]
Eyes: First check the victim for contact lenses
and remove if present. Flush victim’s eyes with water or
normal saline solution for 20?30 minutes while simulta-
neously calling a hospital or poison control center. Do not
put any ointments, oils, or medication in the victim’s eyes
without specific instructions from a physician. Immediately
transport the victim after flushing eyes to a hospital even if
no symptoms (such as redness or irritation) develop. Skin:
Immediately flood affected skin with water while removing
and isolating all contaminated clothing. Gently wash all
affected skin areas thoroughly with soap and water. If
symptoms such as redness or irritation develop, immedi-
ately call a physician and be prepared to transport the vic-
tim to a hospital for treatment. Inhalation: Immediately
leave the contaminated area; take deep breaths of fresh air.
Immediately call a physician and be prepared to transport
the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the
mouth, throat, or chest) develop. Provide proper respiratory
protection to rescuers entering an unknown atmosphere.
Whenever possible, Self-Contained Breathing Apparatus
(SCBA) should be used; if not available, use a level of pro-
tection greater than or equal to that advised under
Protective Clothing. Ingestion: If the victim is conscious
and not convulsing, give one or two glasses of water to
dilute the chemical and immediately call a hospital or poi-
son control center. Generally, the induction of vomiting is
not recommended outside of a physician’s care due to the
risk of aspirating the chemical into the victim’s lungs.
However, if the victim is conscious and not convulsing and
if medical help is not readily available, consider the risk of
inducing vomiting because of the high toxicity of the chem-
ical ingested. Ipecac syrup or salt water may be used in
such an emergency. Immediately transport the victim to a
hospital. If the victim is convulsing or unconscious, do not
give anything by mouth, ensure that the victim’s airway is
open and lay the victim on his/her side with the head lower
than the body. Do not induce vomiting. Immediately trans-
port the victim to a hospital . | [Shipping]
UN1544 Alkaloids, solid, n.o.s. or Alkaloid salts,
solid, n.o.s. poisonous, Hazard Class: 6.1; Labels:
6.1-Poisonous materials, Technical Name Required. | [Incompatibilities]
Riddelline is sensitive to light, air, and
heat, causing oxidation; reacts slowly with atmospheric
oxygen. This chemical is probably combustible; dust mixed with air may be explosive. Incompatible with oxidizers
(chlorates, nitrates, peroxides, permanganates, perchlorates,
chlorine, bromine, fluorine, etc.); contact may cause fires
or explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, and epoxides. Contact with
alkalis and bases may cause hydrolysis. | [Waste Disposal]
It is inappropriate and possi-
bly dangerous to the environment to dispose of expired or
waste product such as lab chemicals by flushing them
down the toilet or discarding them to the trash. Larger
quantities shall carefully take into consideration applicable
EPA, and FDA regulations. If possible return the lab che-
micals to the manufacturer for proper disposal being careful
to properly label and securely package the material.
Alternatively, the waste lab chemicals shall be labeled,
securely packaged and transported by a state licensed medi-
cal waste contractor to dispose by burial in a licensed haz-
ardous or toxic waste landfill or incinerator. |
