1198-56-7 Usage
Appearance
Colorless to light yellow solid Describes the physical appearance of the compound as either colorless or with a light yellow hue in its solid state.
Primary use
Intermediate in chemical production -主要用于作为生产各种化学品（如药品、杀虫剂和染料)的中间体。
Classification
Halogenated aromatic hydrocarbon A type of organic compound containing carbon and hydrogen atoms, with additional halogen atoms (such as chlorine and fluorine) bonded to the aromatic ring.
Environmental impact
Environmental pollutant Due to its toxic effects on aquatic organisms and potential for bioaccumulation in the food chain, it is considered an environmental pollutant.
Health effects
Respiratory and skin irritant Exposure to 1,2,3,5-Tetrachloro-4,6-difluorobenzene can cause irritation in the respiratory system and on the skin.
Human health risks
Adverse health effects Associated with various negative health effects in humans, which can result from direct contact or environmental exposure.
Regulation
Strictly regulated production and use The compound's production and use are regulated to minimize potential risks to the environment and human health.
Check Digit Verification of cas no
The CAS Registry Mumber 1198-56-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1198-56:
(6*1)+(5*1)+(4*9)+(3*8)+(2*5)+(1*6)=87
87 % 10 = 7
So 1198-56-7 is a valid CAS Registry Number.

The preparation of 2,6-difluoroaniline from 1,3,5-trichlorobenzene is described. 1-Chloro-3,5-difluorobenzene prepared via KF exchange on 1,3,5-trichlorobenzene is dichlorinated and nitrated in a single reactor to a mixture of trichlorodifluoronitrobenzenes.The latter are reduced to ca. 4:1 mixture of 2,6-difluoroaniline and 2,4-difluoroaniline.
