Details:

1. Introduction of 1,1-Dichloro-2,2-difluoroethylene (CAS No. 79-35-6)

Our 1,1-Dichloro-2,2-difluoroethylene products are mainly 1,1-Dichloro-2,2-difluoroethylene with the gas chromatography ≥ 97%. For being negligible in water, 3-Bromo-1,1,1-trifluoroacetone is one kind of colorless transparent liquid, with the package of 130KG/steel cylinder. When comes to its storage, it should be kept in a cool, dry, well-ventilated place(Ensure adequate ventilation during use). And its transportation detailes are flammable gas, UN3163, Class: 2.2. 

1,1-Dichloro-2,2-difluoroethylene, for being stable in normal condition, is incompatible with the following materials, such as oxidizing agents, halogens and active metals. Besides, its decomposition products are including carbon monoxide, organic fumes, hydrogen fluoride, and carbonyl fluoride. When comes to its application, 1,1-Dichloro-2,2-difluoroethylene could be applied as the intermediate of the narcotic drug methoxyflurane.

6. Safety information of 1,1-Dichloro-2,2-difluoroethylene (CAS No. 79-35-6)

(Irritant). For being irritating to eyes and skin, 1,1-Dichloro-2,2-difluoroethylene may cause inflammation to the skin or other mucous membranes, and it may toxic by inhalation. Therefore, you should wear suitable protective clothing, gloves and eye/face protection. Remember not to breathe vapour. And if in case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible).

Below are some detailed cases and according measures:
(1). If contact by eyes, immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open.
(2). If contact by skin, you should wash the affected area with water, and remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
(3). If inhalation, you should remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems.
(4). If ingestion, you could seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.
