Zouping Jinxing Tshuaj Co., Ltd. yog ib tug ua manufacturers thiab lwm tus neeg ntawm 2,4-dihydroxybenzoic acid nyob rau hauv Suav teb. Yog tias koj yuav mus rau cov lag luam wholesale bulk 2,4-dihydroxybenzoic acid ua nyob rau hauv Suav teb, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

Cov tsos mob: Cov koob dawb - zoo li cov muaju (crystalizes nrog dej los ntawm cov kua dej; hloov mus rau cov ntawv tsis muaj dej ntawm 100℃); tig liab me ntsis raws li kev cia ntev los yog raug rau lub teeb.
Melting point: 208-211℃(decomposition); ~ 213℃nrog cua kub ceev; daim ntawv anhydrous tuaj yeem ncav cuag 218-219℃nrog cua sov qeeb.
Kub taw tes: ~ 237℃(nrawm kwv yees); nyuaj rau distilled ntawm atmospheric siab vim concurrent decomposition.
Qhov ceev: ~ 1.37 g / cm³ (kwv yees); sim ntsuas tus nqi ~ 1.56 g / cm³.
Solubility: Dej 8 g / L (20 degree); soluble hauv dej kub, ethanol, diethyl ether, acetone, thiab ethyl acetate; yooj yim soluble nyob rau hauv alkaline aqueous daws (ua ntsev); LogP ≈ 0.98 (pH 3.5).
pKa: 3.11 (COOH), 8.55 (phenolic OH), ~ 14 (thib ob phenolic OH) ntawm 25 degree.
UV/FeCl₃: Tsim cov xim liab nrog ferric chloride (tus yam ntxwv ntawm *ortho*-phenolic hydroxyl pawg); feem ntau siv rau kev txheeb xyuas.
Flash point: ~ 200 degree; combustible khoom; tsis suav tias yog cov nplaim taws heev lossis tawg.

Pharmaceutical intermediates: Synthesis ntawm mycophenolic acid, PDE4 inhibitors, HSP90 inhibitors, hydroxylated xanthenes, thiab lwm yam.
Dyes/Coupling Cheebtsam: Azo dye intermediate (Coupler 320)
Kev soj ntsuam reagents: Spot test rau Fe³⁺ (xim cov tshuaj tiv thaiv), colorimetric txiav txim siab ntawm Ti, thiab lwm yam.; MALDI-MS matrix (polymer)
Khoom noj khoom haus flavoring: FEMA 3798, GRAS; taug qab antioxidant flavouring rau cov dej txias, dej haus, thiab khoom qab zib (qib dej txias: 450 mg / kg)
Nroj / Metabolite: Ib txwm tshwm sim hauv cov qos yaj ywm thiab txiv maj phaub; tib neeg urinary metabolite

Toxicity: Low toxicity. Intraperitoneal LD₅₀ in mice >800 mg / kg; tsawg qhov ncauj txaus ntshai nyob rau hauv nas; ua rau tawv nqaij, qhov muag, thiab ua pa (R36/37/38).
GHS: Xi (Irritant); Kev tiv thaiv tus qauv (piv txwv li, P261/P264/P280).
Cia thiab Thauj: Khaws rau hauv lub thawv kaw, tiv thaiv lub teeb, ntawm chav tsev kub (<30°C) or in a cool, dry place; keep separate from strong oxidizers; not classified as hazardous for transport (NONH).
