SYMPTOMS: Symptoms of exposure to this compound may include toxic epidermal necrolysis with pseudomembranous conjunctivitis and ulceration of the lids and conjunctivae of both corneas. Cataracts may also occur. It may also cause Lesch-Nyhan syndrome, lymphosarcoma, reduced serum and urinary uric acid levels, hepatotoxicity, drowsiness, xanthine crystalluria, death (rare), myeloma, congestive myocardial disease, painful urination, blood in the urine, swelling of the lips and mouth, alkaline phosphatase increase, SGOT/SGPT increase, acute attacks of gout, ecchymosis, necrotizing angiitis, hepatic necrosis, hyperbilirubinemia, gastritis, dyspepsia, thrombocytopenia, myopathy, peripheral neuropathy, neuritis, paresthesia, somnolence, epistaxis, Lyell's syndrome, purpura, dermatitis and salivary gland swelling. Other symptoms may include skin rashes, fever, nausea, vomiting, diarrhea, leukopenia and eosinophilia. Reversible liver impairment may also occur. Exposure may cause maculopapular rashes, pruritus, abdominal pain, malaise and headaches. Exposure may also cause erythematous skin eruptions, aching muscles, bone marrow depression, vertigo and gastric irritation. It may also cause exfoliative lesions, urticaria, purpuric skin rash, hepatomegaly and peripheral neuritis. Other symptoms of exposure to this chemical may include chills, leukocytosis, Stevens-Johnson syndrome, vasiculitis, anorexia, severe weight loss, acute renal failure, aplastic anemia and agranulocytosis. Exposure may also lead to hypersensitivity, arthralgia, alopecia, liver damage, oxypurine calculi, xanthine stones, ichthyosis, general weakness, severe allergic reactions, hepatic abnormalities, neutropenia, oliguria, uremia, extensive intracutaneous infections, sepsis, pneumonia, hepatic necrosis, cholangitis, pericholangitis, jaundice, lymphadenopathy, granulomas in the liver, nephritis, severe arteritis and sarcoidoisis. Muscle weakness may occur. ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes of nitrogen oxides. (NTP, 1992)
Treatment for hypersensitivity reaction: Administer glucocorticoids. Prolonged administration may be required after a severe reaction.
Water spray, dry chemical, carbon dioxide, or foam as appropriate for surrounding fire and materials.
Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
Wear self-contained breathing apparatus for firefighting if necessary.
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Wipe up spillage or collect spillage using a high- efficiency vacuum cleaner. Avoid breathing dust. Place spillage in appropriately labeled container for disposal. Wash spill site.
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Store in tight container as defined in the USP-NF. This material should be handled and stored per label instructions to ensure product integrity.

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

4-HYDROXYPYRAZOLO(3,4-D)PYRIMIDINE is an amine derivative. 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. This chemical darkens above 572° F, and at an indefinite high temperature, it chars and decomposes. At 221° F, maximum stability occurs at pH 3.1- 3.4. This chemical decomposes in acidic and basic solutions.

An estimated BCF of 3 was calculated in fish for allopurinol(SRC), using a log Kow of -0.55(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
The Koc of allopurinol is estimated as 71(SRC), using a log Kow of -0.55(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that allopurinol is expected to have high mobility in soil.

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
