1. BTC is the abbreviation of (Trichloromethyl) carbonate. It is the abbreviation of a chemical substance, mainly composed of carbon, chlorine and oxygen. The chemical formula is c3cl6o3, which can be used as the substitute proct of highly toxic phosgene and diphosgene in the synthesis
BTC = bis (Trichloromethyl) carbonate, namely triphosgene
CAS Registry number32315-10-9
molecular formula c3cl6o3
molecular weight 296.748
extended data:
triphosgene is used as a reagent in organic synthesis, and is a less dangerous substitute for phosgene used in various chemical transformations, including bonding one carbonyl group to two alcohols and converting amino group to isocyanate
The toxicity of Triphosgene is the same as that of phosgene because it decomposes into phosgene when heated and reacted with nucleophiles. Even a small amount of water can lead to the formation of phosgene. Therefore, if all precautions are taken for phosgene, the reagent can be handled safely
as a substitute of highly toxic phosgene and diphosgene in synthesis, this proct has low toxicity, safe and convenient use, mild reaction conditions, good selectivity and high yield
this proct is a class II organic drug. It should be stored in a dry, cool and ventilated warehouse, away from fire source, and separated from organic amines and alkaline chemicals
2. You can only buy the genuine one

3. Walk 200m to meinian university physical examination center
4. You said these are professional physical examination center, because only do physical examination, so professional will be stronger; Now, the official account of dolphin health platform can make all the medical examinations, including Nanchang, East Lake, Xihu District, Qingyun District, Wanli District, Qingshan Lake area and new district. Meinian health is a listed company. There are hundreds of chain stores across the country, which is the largest physical examination center at present. Ciming was acquired by meinian health. Aikang Guobin is also a listed company. There are dozens of chain stores across the country, which are relatively small, but the price is the highest. The key lies in the demand for physical examination!

6. Many people who want to travel to Thailand are paying attention to the safety of Thai tourism. In fact, you can rest assured about the safety of Thailand's tourism. Thailand is very safe now. I went to Thailand for a month in February this year. I was deeply impressed by Thailand's Dawang palace, jade Buddha Temple, simian Buddha and Tussauds Wax Museum. I also enjoyed the beautiful scenery of Phuket and Sumi. Another guide to you is the official website of Thailand tourism bureau, which not only has many introctions about Thai culture and scenic spots and other tourism information, but also has a help line, which may be helpful to you. Finally, I wish you an unforgettable trip to Thailand!
