3,5-Dinitrobenzoic Acid

Zouping Jinxing Tshuaj Co., Ltd. Yog tias koj yuav mus rau cov lag luam wholesale bulk 3,5-dinitrobenzoic 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.

CAS: 99-34-3 Nr
Cov tsos mob: Dawb mus daj daj crystalline hmoov (tej zaum yuav tshwm daj me ntsis nyob ntawm purity los yog lub teeb raug)
Melting point: 205-207℃(melted ua ntej sublimation; qee cov ntaub ntawv hais txog 208 degree)
Boiling point: >300℃(nrog decomposition)
Qhov ceev: kwv yees li . 1.68 g/cm³
Solubility: Sparingly soluble hauv dej (<0.1 g/100 mL at room temperature); readily soluble in ethanol, acetone, ethyl acetate, and hot methanol; dissolves in alkaline aqueous solutions (e.g., NaOH) by forming a salt
pKa: Kwv yees li . 2.8 (ntau acidic tshaj benzoic acid, uas muaj pKa ntawm 4.2, vim muaj zog electron - rho tawm cov nyhuv ntawm ob pawg nitro)
UV: muaj zog nqus; λmax ntawm approx . 230 nm thiab 330 nm (tus yam ntxwv ntawm nitro- hloov aromatic acids)

Analytical Chemistry: Kev npaj ntawm cawv, phenol, thiab amine derivatives + melting point identification (tshwj xeeb tshaj yog rau kev qhia txog cov organic chemistry thwmsim)
Organic Synthesis Intermediates: Kev tsim cov diaminobenzoic acid, azo dyes, thiab kws tshuaj sab chains
Chromatographic Derivatization Reagents: Derivatization ntawm cawv hauv HPLC / TLC los txhim kho kev tshawb pom rhiab heev
Corrosion / Corrosion Inhibition Research: Hlau nto kho additives (hauv me me)

Toxicity: Toxic dosage. Qhov ncauj LD₅₀ hauv nas ≈ 300–600 mg / kg (nitroaromatic acids ua rau muaj kev pheej hmoo ntawm hepatotoxicity ntau ntxiv).
Irritation: Plua plav ua rau lub ntsws ua pa, qhov muag, thiab tawv nqaij; muaj peev xwm rau rhiab heev.
GHS: H302 Ua phem yog tias nqos; H315 Ua rau tawv nqaij khaus; H319 Ua rau mob qhov muag loj; H335 Tej zaum yuav ua rau ua pa ua pa.
Cia thiab thauj: Khaws rau hauv lub thawv kaw, tiv thaiv lub teeb thiab noo noo; cais tawm ntawm cov oxidizing cov neeg ua haujlwm (muaj cov pab pawg nitro tab sis tsis yog cov khoom tawg yooj yim; kom deb ntawm cov neeg ua kom muaj zog los tiv thaiv kev tsim cov amines); ua raws li cov kev cai rau cov tshuaj lom neeg.
