2 3 5-Trichloropyridine 98% Trihalopyridine

Our 2,3,5-Trichloropyridine 98% waxay bixisaa falcelis kala duwan ee beerochemical iyo synthesis dawooyinka adduunka oo dhan. CAS 16063-70-0 simmetrical trihalopyridine (2,3,5-TCP) waxay ku guulaysataa ≥98.0% daahirnimada GC ≤1.0% isomeric trichloropyridines iyo ≤0.3% tetrachloropyridine — regioselectivity kaagu wuxuu u baahan yahay beddelaad.

Sida C₃-symmetric electrophile oo isku dhafan, 2,3,5-TCP waxay awood u siineysaa shaqeynta tallaabo tallaabo iyada oo loo marayo beddelka udgoonka nucleophilic ee xulashada. 2- iyo 6-meelood waxay si doorbidan u dhaqaajiyaan dhanka nucleophiles-ada adag, halka booska 3-aad uu u baahan yahay xaalado adag, taasoo u oggolaanaysa tafatirka orthogonal. Waxay u adeegtaa sidii horudhaca furaha ee chlorpyrifos iyo chlorpyrifos-methyl cayayaanka, oo ah dhismo loogu talagalay nicotinic acetylcholine receptor modulators, iyo dhexdhexaad u ah dawooyinka pyridine halogenated. Atamyada chlorine-ka ee soo hadhay waxa ay u adeegaan sidii gacanta Suzuki, Negishi, iyo Buchwald-Hartwig isku xidhka kadib bedelkii hore.

Fasalada la heli karo: Heerka 98%, Nadiif-sare 99% (<0.5% isomers), darajada aysiidh-hooseeya (<0.01% HCl), Foom dib-u-crystallized oo khaas ah.

Baakadaha: 250kg/DRUM durbaannada birta ah ee epoxy-ku dahaaran oo buste nitrogen ah; 1000L IBC ee ololaha tirada badan. Barta dhalaalka hoose ee adag (mp 46-49°C); u qabo sida dareere dhalaalay ama adag oo ku xidhan heerkulka deegaanka. Duubista UV-opaque waxay ka hortagtaa photodechlorination.

Maareynta Muhiimka ah: Cuncun maqaarka iyo mareenka neefsashada; iska ilaali siigada jiilka. Ku xasiloon xaaladaha caadiga ah laakiin waxaa laga yaabaa inay si tartiib tartiib ah hawada qoyan ugu shubto 2,3,5-trichloro-6-pyridinol. REACH isdiiwaan gelinta; TSCA ku qoran. SDS dhamaystiran oo leh aqoonsiga isomer, borotokoolka beddelka hab-nololeedka, iyo dekloriinta qashinka (catalytic hydrogenation).

Sahayda: U dhoofinta tooska ah ee Hindiya, Shiinaha, USA, Jarmalka, Brazil, iyo 35+ suuqyo. COA buuxa oo leh astaanta GC isomer profile, barta dhalaalka, iyo xogta falcelinta u gaarka ah booska.

Codso xigashadaada 2,3,5-Trichloropyridine 98% 24 saacadood gudahood—qandaraasyo badan, muunado heer sare ah oo nadiif ah, iyo chlorpyrifos synthesis la tashiyo ayaa diyaar ah.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
