Chemical Properties
green crystalline powder
Uses
Sensitizer for photographic emulsions.
General Description
Green, needle-like crystals. Used as a veterinary anthelmintic, as a sensitizer for photographic emulsions and as an insecticides. Not registered as a pesticide in the U.S.
Reactivity Profile
An amine, organosulfide. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Health Hazard
Highly toxic by mouth. (Non-Specific -- Pesticide, Solid, n.o.s.) Poisonous if swallowed, or if dust is inhaled.
Fire Hazard
When heated to decomposition, 3,3'-DIETHYLTHIADICARBOCYANINE IODIDE emits toxic fumes of iodine, sulfur oxides, and nitrogen oxides.
Description
Dithiazanine iodide is a green, needle-likecrystalline solid which decomposes at 248℃. Sulfur-likeodor. Molecular weight= 519.51. Melting point 5 225℃;Hazard Identification (based on NFPA-704 M RatingSystem): Health 3, Flammability 0, Reactivity 1. Insolublein water.
Originator
Delvex,Lilly,US,1958
Manufacturing Process
3.05 g of 1-methylbenzthiazole ethiodide, 1.11 g of β-ethyl thio acrolein
diethyl acetal and 15 cc of pyridine were mixed and boiled gently under reflux
for 15 minutes. The reaction mixture was then poured into an aqueous
solution of potassium iodide. The dye was precipitated and was filtered off,
and washed with ethyl alcohol and ether. Recrystallization from methyl alcohol
solution yielded the dye as green needles. Melting point 248°C with
decomposition.

Therapeutic Function
Anthelmintic
World Health Organization (WHO)
Dithiazanine iodide, an anthelminthic, was introduced in 1959 for
the treatment of strongyloid worms and whipworms. Between 1961 and 1964 its
use was associated with eight fatal cases of severe acidosis and shock. Although
the drug is not significantly absorbed from the gut, in normal circumstances it was
assumed that these fatalities were due to atypically high uptake from inflamed
intestinal mucosa. Dithiazanine iodide has been superseded by safer and more
effective drugs; however, it may remain available in some countries.
Potential Exposure
This material is used as a plasticizer,as a rubber accelerator; and as an intermediate inmanufacturing of pesticides
First aid
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.
storage
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area.
Shipping
Pesticides, solid, toxic, n.o.s. have a labelrequirement of “POISONOUS/TOXIC MATERIALS.”They fall in Hazard Class 6.1 and this material in PackingGroup II.
Incompatibilities
Stable under normal conditions of temperature and pressure. Keep away from alkalies, strongoxidizers.
