CAS: 1536473-72-9|TBuBrettPhos Pd G3

Cov khoom sib xyaw ua ke rau CAS 1536473-72-9 yog TBuBrettPhos Pd G3, uas belongs rau phosphine ligand complex hauv palladium catalytic system. Nws cov mis molecular yog C44H63NO5PPdS, thiab nws qhov hnyav molecular yog li 854.43 g / mol.
TBuBrettPhos Pd G3 muaj di-tert-butylphosphine ligands, uas ua ke nrog cov methoxy thiab isopropyl pawg ntawm biphenyl skeleton los tsim ib tug qauv nrog loj steric hindrance, uas pab lub selectivity ntawm palladium catalytic cov tshuaj tiv thaiv thiab qhia tau hais tias siab catalytic kev ua tau zoo.

Khoom:

1. Nws yog qhov ruaj khov nyob rau hauv ib txwm muaj, tab sis yuav raug oxidation lossis decomposition tshwm sim nyob rau hauv tej yam kev mob uas muaj oxygen los yog high humidity.
2. Raws li cov organic compound ntawm palladium, nws feem ntau yog siv los ua cov catalyst lossis nruab nrab hauv cov tshuaj tiv thaiv. Nws tuaj yeem ua rau muaj kev cuam tshuam ntau cov organic, xws li hydrogenation, coupling, oxidation, thiab lwm yam.
3. Feem ntau nws tuaj yeem yaj hauv cov kuab tshuaj organic xws li methanol, ethanol, chloroform, thiab lwm yam.

Kev siv:

TBuBrettPhos Pd G3 feem ntau yog siv rau C-C daim ntawv cog lus sib txuas cov tshuaj tiv thaiv xws li Suzuki-Miyaura thiab Negishi coupling, nrog rau kev tsim cov molecules nyuaj xws li nitrogen- muaj cov heterocycles thiab biphenyl compounds, thiab feem ntau siv hauv kev tshawb fawb thiab kev loj hlob ntawm cov chaw muag tshuaj.

1. Toxicity: TBuBrettPhos Pd G3 yog cov tshuaj lom neeg. Kev sib cuag ncaj qha lossis nqus tau cov tshuaj ntau yuav ua rau muaj cov tsos mob lom xws li ua pa nyuaj, mob hauv siab, xeev siab, ntuav thiab mob taub hau.

2. Irritant: Cov khoom xyaw yuav ua rau lub qhov muag, tawv nqaij thiab ua pa.

3. Kev pheej hmoo hluav taws kub thiab tawg: Cov khoom siv hluav taws xob tuaj yeem hlawv lossis tawg nyob rau hauv cov xwm txheej kub kub, qhib nplaim taws lossis sparks. Tsis txhob sib cuag nrog cov khoom siv hluav taws xob thiab khaws cia hauv qhov chaw txias, qhuav.

4. Cia thiab tuav: Lub compound yuav tsum muab cia rau hauv lub thawv kaw kom deb ntawm hluav taws thiab oxidants. Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes tiv thaiv, tsom iav tiv thaiv thiab lub ntsej muag tiv thaiv yuav tsum hnav thaum siv.

Lub sij hawm tsim lub tuam txhab: 2021; Factory cheeb tsam: 3600 square meters. Tuam txhab cheeb tsam: 800 square meters. Cov neeg ua haujlwm hauv tuam txhab: 200+
