CAS number: 556-61-6
Methyl isothiocyanate is an isothiocyanate having a methyl group attached to the nitrogen. It is also the active nematicide of the pronematicide metam-sodium. It has a role as a fumigant, a nematicide and a lachrymator.
Synthesis of the anion PET sensors 1–3, from 9-(aminomethyl)anthracene 5, and phenyl-, 4-(trifluoromethyl)phenyl-, and methyl isothiocyanates, giving 1, 2 and 3 respectively.
CAS number: 557-20-0
Diethylzinc is an organozinc compound. It is used as a reagent in organic chemistry and in liquid rocket fuel. Zinc is a metallic element with the atomic number 30. It is found in nature most often as the mineral sphalerite. Though excess zinc in harmful, in smaller amounts it is an essential element for life, as it is a cofactor for over 300 enzymes and is found in just as many transcription factors.
Synthesis of Optically Active Allyl Carbamate by Enantioselective Addition of Diethylzinc.
CAS number: 55750-48-6
N-Methoxycarbonylmaleimide, also known as N-(Methoxycarbonyl)maleimide, is a synthetic organic compound. It's a maleimide derivative, meaning it contains a five-membered ring with two carbonyl groups and a nitrogen atom. The methoxycarbonyl group (-COOCH3) is attached to the nitrogen, making it a useful reagent for introducing a maleimide group into other molecules.

CAS number: 558-13-4
Carbon tetrabromide, also known as tetrabromomethane, is a chemical compound with the formula CBr₄.
(A) The structure was optimized by DFT under vacuum conditions using the ωB97X-D function, 6-311G(d,p) for C,H, 6-311+G(d,p) for N,S, and Def2TZV for Br. (B) The electrostatic potentials of N-methylthioamide and tetrabromomethane were calculated on a 0.0004 au isodensity surface (ωB97X-D/Def2TZV) (red = negative electrostatic potential, blue = positive electrostatic potential).
CAS number: 55881-07-7
Miocamycin is a macrolide type antimicrobial. This drug may be marketed in Japan for clinical use as it is listed in the Japanese pharmacopeia. It has shown to be effective against several gram-positive and gram-negative microbes and may be useful in the treatment of upper and lower respiratory tract infections, and urogenital tract infections or as an alternative to erythromycin treatment.
