3-pyridinextulfonic acid are cas 636-73-7

1. Tshuaj Nruab Nrab

Feem ntau siv los ua nruab nrab hauv synthesis ntawm cov khoom xyaw tshuaj muaj zog (APIs).

Nws cov sulfonic acid pawg imarars dej solubility thiab reassonity, pab tau rau txuas rau ntau yam kws tshuaj.

2. Catalysis thiab organocatalyststions

Ua hauj lwm ua cov txiv ntoo lossis co-catalyst nyob rau hauv kev hloov tsheb hlau-catalyzed vim nws nitrogen thiab sulfonic acid ua haujlwm.

Txhim kho solubility thiab electron-rho tawm cov yam ntxwv hauv acid-catalalyzed organic transformations.

3. Dye thiab Xim Kev Lag Luam

Siv hauv kev tsim cov AZO dyes, qhov uas nws ua raws li kev sib koom ua ke lossis tus neeg sawv cev kom nce dej solubility thiab ci ci.

4. Polymer hloov kho

Yuav muaj kev koom tes rau hauv cov haujlwm polymers los qhia cov acidic chaw rau ion pauv cov resins, membrane cov khoom siv, lossis cov khoom siv proton-ua.

5. Kev txheeb xyuas Chemiser

Siv nyob rau hauv derivatinization kev xav tau los yog li ib matrix hloov kho hauv cov txuj ci xws li chromatography lossis huab hwm coj huab hwm hluav taws xob.

1. Ob Pab Pawg Ua Haujlwm

Muaj ob qho tib si ntawm cov nitrogen (los ntawm lub nplhaib pyridine) thiab muaj zog acidic sulfonic pawg, muab ntau yam kev pheej hmoo.

Pab tau nyob rau hauv cov ntawv thov bifunctions xws li cov kua qaub-hauv paus catalysis lossis ionic sib xyaw synthesis.

2. Cov dej solubility siab

Sulfonic acid pawg ua kom tau zoo solubility hauv aqueous meus me me, uas tau txais txiaj ntsig hauv cov txheej txheem kev lag luam lossis cov txheej txheem dej.

3. Ruaj khov nyob rau hauv cov xov tooj dav

Chemically tsis khov, tswj cov qauv txheej txheem hauv ob qho tib si acidic thiab ib puag ncig.

4. Cov qauv sib txawv

Qhov 3-txoj hauj lwm hloov cov pyridine tso cai rau cov khoom sib txawv ntawm cov khoom sib txawv thiab cov khoom siv hluav taws xob, muaj txiaj ntsig rau kev sib tw hauv heterocyclic sib xyaw synthesis.
