The IUPAC name of Carbidopa is (2S)-3-(3,4-dihydroxyphenyl)-2-hydrazinyl-2-methylpropanoic acid. With the CAS registry number 28860-95-9, it is also named as (-)-L-alpha-Hydrazino-3,4-dihydroxy-alpha-methylhydrocinnamic acid; Hadrazino-alpha-methyldopa. The product's categories are L-Aromatic Amino Acid Decarboxylase. It is powder which is toxic. When heated to decomposition it emits toxic fumes of NOx. So the storage environment should be ventilate, low-temperature and dry.

The other characteristics of this product can be summarized as: (1)ACD/LogP: -0.19; (2)# of Rule of 5 Violations: 1; (3)ACD/LogD (pH 5.5): -2.54; (4)ACD/LogD (pH 7.4): -2.76; (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: 6; (11)#Freely Rotating Bonds: 7; (12)Index of Refraction: 1.641; (13)Molar Refractivity: 57.49 cm³; (14)Molar Volume: 159.2 cm³; (15)Polarizability: 22.79×10^-24 cm³; (16)Surface Tension: 74 dyne/cm; (17)Enthalpy of Vaporization: 84.58 kJ/mol; (18)Vapour Pressure: 5.27E-12 mmHg at 25°C; (19)Rotatable Bond Count: 4; (20)Tautomer Count: 18; (21)Exact Mass: 226.095357; (22)MonoIsotopic Mass: 226.095357; (23)Topological Polar Surface Area: 116; (24)Heavy Atom Count: 16.

Uses of Carbidopa: It can inhibit an enzyme which is important in the biosynthesis of L-tryptophan to serotonin and in the biosynthesis of L-DOPA to Dopamine. So it is used as peripheral decarboxylase inhibitor and used in combination with levodopa for treatment of Parkinsonism. The combination of carbidopa/levodopa enhances the bioavailability of carbidopa and levodopa. It is also used in combination with 5-HTP, a naturally occurring amino acid which is a precursor to the neurotransmitter serotonin and an intermediate in tryptophan metabolism.
