Specification
The IUPAC name of D(-)-Tartaric acid is 2,3-dihydroxybutanedioic acid. With the CAS registry number 526-83-0, it is also named as Butanedioic acid, 2,3-dihydroxy-. The product's category is Food & Flavor Additives. It is a white crystalline diprotic organic acid. And it occurs naturally in many plants, particularly grapes, bananas, and tamarinds, and is one of the main acids found in wine. What's more, this chemical is chiral, meaning that it has molecules that are non-superimposable on their mirror-images.
The other characteristics of this product can be summarized as: (1)ACD/LogP: -1.43; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -5.86; (4)ACD/LogD (pH 7.4): -6.18; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 1; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 6; (10)#H bond donors: 4; (11)#Freely Rotating Bonds: 5; (12)Index of Refraction: 1.585; (13)Molar Refractivity: 26.69 cm3; (14)Molar Volume: 79.5 cm3; (15)Polarizability: 10.58×10-24 cm3; (16)Surface Tension: 119.4 dyne/cm; (17)Enthalpy of Vaporization: 75.13 kJ/mol; (18)Vapour Pressure: 4.93E-08 mmHg at 25°C; (19)Rotatable Bond Count: 3; (20)Exact Mass: 150.016438; (21)MonoIsotopic Mass: 150.016438; (22)Topological Polar Surface Area: 115; (23)Heavy Atom Count: 10; (24)Complexity: 134.
Uses of D(-)-Tartaric acid: It is added to other foods to give a sour taste, and is used as an antioxidant. It also plays an important role in the discovery of chemical chirality. This chemical is a useful raw material in organic chemistry for the synthesis of other chiral molecules. In addition, it can react with (6,7-dimethoxy-1,2,3,4-tetrahydro-isoquinolin-1-yl)-methanol to get 2,3-dihydroxy-succinic acid mono-(6,7-dimethoxy-1,2,3,4-tetrahydro-isoquinolin-1-ylmethyl) ester. The yield is 31%.
