The latter process provides a high-yield route to 1,1-binaphthol: [22] Such compounds are intermediates in the synthesis of BINAP and its derivatives. [20] Copper(II) chloride dihydrate promotes the hydrolysis of acetonides, i.e., for deprotection to regenerate diols [23] or aminoalcohols, as in this example (where TBDPS = tert ...
Copper(I) chloride is produced industrially by the direct combination of copper metal and chlorine at 450–900 °C: [11] [12] 2 Cu + Cl 2 → 2 CuCl Copper(I) chloride can also be prepared by reducing copper(II) chloride with sulfur dioxide , or with ascorbic acid ( vitamin C ) that acts as a reducing sugar : [ 13 ] [ 14 ]
C 12 H 14 O 4: dillapiole: C 12 H 15 NO: 1-benzyl-4-piperidone: 3612-20-2 C 12 H 16 N 2: N,N-Dimethyltryptamine: 61-50-7 C 12 H 16 O 3: asarone: C 12 H 16 O 3: elemicin: C 12 H 16 O 3: isoelemicin: C 12 H 16 O 3: oudenone: C 12 H 16 O 4: 2,4,5-Trimethoxypropiophenone: C 12 H 16 O 7: arbutin: 497-76-7 C 12 H 17 N 5 O 4 S thiamine nitrate: C 12 H ...
12 NaCuCl 2 + 3 O 2 + 2 H 2 O → 4 Cu 2 (OH) 3 Cl + 4 CuCl 2 + 12 NaCl. The product from this process is of fine particle with size of 1 ~ 5 μm and is usable as an agricultural fungicide. [6] Astable, free-flowing, non-dusty green powder with typical particle size of 30 ~ 100 microns has been used in preparation of uniform animal feed ...
Cyanuric chloride is employed as a reagent in organic synthesis for the conversion of alcohols into alkyl chlorides, [8] and carboxylic acids into acyl chlorides: [9]. It is also used as a dehydrating agent, e.g. in the conversion of amides to nitriles, [10] and for the activation of carboxylic acids for reduction to alcohols.
The LD50 (oral, rats) is 756 mg/kg. Animal studies have shown that 1,2,4-trichlorobenzene affects the liver and kidney, and is possibly a teratogen. [4] There is no regulated occupational exposure limit for chemical exposure, but the National Institute for Occupational Safety and Health recommends no greater exposure than 5 ppm, over an 8-hour workday.
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br.It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers.

Penicillamine, sold under the brand name of Cuprimine among others, is a medication primarily used for the treatment of Wilson's disease. [1] It is also used for people with kidney stones who have high urine cystine levels, rheumatoid arthritis, and various heavy metal poisonings. [1] [2] It is taken by mouth. [2]
