Appearance：

C.i. acid red 97 is a red to dark red powder. Copper and iron dull color; iron to a greater extent. (NTP, 1992)

Melting Point：

greater than 572° F (NTP, 1992)

Water Solubility：

In water, 1 to 10 mg/mL at 68° F (NTP, 1992)

Air and Water Reactions：

Azo dyes in powder form can be explosive when suspended in air at specific concentrations. Moderately soluble in water to give acidic solution.

Reactive Group：

Azo, Diazo, Azido, Hydrazine, and Azide Compounds

Reactivity Profile：

Aqueous solutions react as acids to neutralize bases in weakly exothermic reactions. Toxic gases are formed by mixing with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.

Fire Hazards：

Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)

GHS Classification：

|Danger|H319 (83.18%): Causes serious eye irritation [Warning Serious eye damage/eye irritation]|P201, P202, P264, P273, P280, P281, P305+P351+P338, P308+P313, P337+P313, P391, P405, and P501|Aggregated GHS information provided by 620 companies from 9 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.

Fire Fighting：

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. A water spray may also be used. (NTP, 1992)

Nonfire Spill Response：

SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. STORAGE PRECAUTIONS: You should store this material under ambient temperatures. (NTP, 1992)

Personal Protective Equipment：

RECOMMENDED RESPIRATOR: Where the neat test chemical is stored, weighed and diluted, wear an approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Drug Information

Health Hazards：

ACUTE/CHRONIC HAZARDS: When heated to decomposition this chemical emits toxic fumes of nitrogen oxides. (NTP, 1992)

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 to 30 minutes while simultaneously 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, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. 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 protection greater than or equal to that advised under Protective Clothing. INGESTION: If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. 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 transport the victim to a hospital. (NTP, 1992)
