3,4-Dichlorobenzoic acid C화학적 특성, 용도, 생산
화학적 성질
White to light yellow crystal powder용도
3,4-Dichlorobenzoic acid was employed as internal standard during the multiresidue analysis of pharmaceuticals and personal care products by ultra performance liquid chromatography-positive/negative electrospray tandem mass spectrometry. It was used to study the metabolic fate of 4-chloro-3,5-dinitrobenzoic acid.정의
ChEBI: A chlorobenzoic acid carrying chloro substituents at positions 3 and 4.Safety Profile
Poison by subcutaneous route. When heated to decomposition it emits toxic fumes of Cl-.Purification Methods
Crystallise the acid from aqueous EtOH (charcoal) or acetic acid. [Beilstein 9 IV 1006.] Aromatic acid impurities (to <0.05%) can be removed via the (±)--methylbenzylamine salt as described for 2,4-dichlorobenzoic acid [Ley & Yates Organic Process Research & Development 12 120 2008.]3,4-Dichlorobenzoic acid 준비 용품 및 원자재
