Citric acid is a weak organic acid that is known as a commodity chemical, as more than a million tonnes are produced every year by mycological fermentation on an industrial scale using crude sugar solutions, such as molasses and strains of Aspergillus niger. Citric acid is widely distributed in plants and in animal tissues and fluids and exist in greater than grace amounts in variety of fruits and vegetables, most notably in citrus fruits such as lemon and limes. Citric acid is mainly used as an acidifier, flavoring agent and chelating agent.||Synonyms: |2-Hydroxy-1,2,3-propanetricarboxylic Acid; 2-Hydroxy-1,2,3-propanetricarboxylic Acid; 2-Hydroxypropan-1,2,3-tricarboxylic Acid; 3-Carboxy-3-hydroxypentane-1,5-dioic Acid; Aciletten; Celenex 3P6; Cellborn SC-C; Chemfill; Citretten; Citric Acid Monoglyceride; Citro; E 330; EL 4; EL 4; F 0001; F 4020; FE 2; Grindsted Pro Tex TR 100; Hydrocerol A; INS 330; Jet Setter; Monoglyceride Citrate; NSC 112226; NSC 30279; NSC 626579; Suby G; Uro-trainer ||CAS No: |77-92-9 ||Molecular Formula: |C6H8O7||Molecular Weight: |192.12||Purity (Titration): |≥99.5%||Appearance: |White cystalline powder||Solubility: |Colorless, clear, complete in DMSO, Methanol.||Insoluble Matter:|≤0.005%||Residue after Ignition:|≤0.02%||Chloride:|≤0.001%||Oxylate:|To Pass Test||Phosphate:|≤0.001%||Sulfate:|≤0.002%||Lead:|≤0.0002%||Iron:|≤0.0003%||Substances Carbonizable by hot H2SO4 (Tartates, etc.):|To Pass Test||Storage: |RT||Meets or exceeds ACS Specifications
