● Textiles
● Tawv
● Daim ntawv
Cov pab pawg amine tau dhau los ua diazotization los tsim cov ntsev diazonium, uas tom qab ntawd ua ke nrog cov tshuaj tsw qab los ua cov yeeb yuj azo dyes xws li:
● Methyl txiv kab ntxwv
● Congo liab
● Acid txiv kab ntxwv 7
B. Brightening Agents
Siv los tsim kho qhov muag teeb pom kev zoo uas txhim kho cov ntaub ci ntsa iab los ntawm kev hloov UV teeb rau pom lub teeb.

2. Kev tshuaj xyuas Chemistry
A. Griess Reagent Component
Sulfanilic acid yog ib qho tseem ceeb ntawm Griess reagent, dav siv los kuaj xyuas nitrite ions hauv:
● Cov qauv dej ib puag ncig
● Cov kua roj ntsha lom
● Kev kuaj zaub mov
Kev kuaj Griess suav nrog diazotization ntawm sulfanilic acid thiab cov tshuaj tiv thaiv nrog N-(1-naphthyl)ethylenediamine, tsim cov xim liab azo rau kev kuaj pom xim.
B. Calibration Standard
Vim nws cov khoom ruaj khov, sulfanilic acid yog siv los ua tus qauv tseem ceeb hauv calibration ntawm spectrophotometers thiab lwm yam twj paj nruag.

3. Kev lag luam kws tshuaj
Txawm hais tias tsis yog feem ntau siv ncaj qha los ua tshuaj, sulfanilic acid yog lub tsev thaiv hauv kev sib xyaw ntawm sulfa tshuaj (sulfonamides), uas muaj cov tshuaj tua kab mob.

4. Electrochemical thiab Industrial Applications
A. Corrosion Inhibitors
Hauv qee cov formulations, sulfanilic acid derivatives yog ntxiv rau cov hlau tiv thaiv kab mob raws li corrosion inhibitors vim lawv muaj peev xwm chelate hlau ions thiab tsim cov yeeb yaj kiab tiv thaiv.
B. Polymers thiab Txheej
Nws yog siv los ua monomer los yog additive nyob rau hauv zus tau tej cov conductive polymers, resins, thiab plasticizers, tshwj xeeb tshaj yog thaum sulfonic pawg xav tau rau ionic conductivity.

5. Kev siv ib puag ncig
Sulfanilic acid 丨 CAS 121-57-3 plays lub luag haujlwm hauv kev tshawb fawb txog kev kho dej khib nyiab thiab kev tshawb fawb photocatalysis ua tus qauv ua paug rau kev soj ntsuam:
● Photodegradation kinetics
