In terms of chemical, the market has been segmented into stilbene, coumarin, diphenyl pyrazoline, and others (including dicarboxylic acid
and cinnamic acid).
* Azelaic Acid - A dicarboxylic acid
recommended for its skin lightening and anti-acne benefits.
Based on their previous work demonstrating that azelaic acid, a saturated dicarboxylic acid
found naturally in wheat, rye, and barley, suppressed melanogenesis, Yu and Kim investigated the antimelanogenic activity of azelaic acid and taurine in B16F10 mouse melanoma cells in 2010.
* Azelaic acid: naturally occurring nine-carbon dicarboxylic acid
. 20% azelaic acid cream--antibiotic activity against P.
A nucleation agent such as a calcium salt of 1,2 cyclohexane dicarboxylic acid
enables low shrinkage.
Then the reaction solution was chilled to 0[degrees]C in the ice bath and 6.270 mmol of a dipropargyl ester of dicarboxylic acid
, 238.8 mg (1.254 mmol) of catalyst CuI (20 mol%), and 0.874 mL (6.270 mmol) of TEA as a ligand were added to the reaction solution.
Pyridine dicarboxylic acid
derivatives are a kind of important organic ligands, which have rigid conjugated structures and rich coordination forms with the wide application in optical fiber communication system and the time resolution of fluorescence immunoassay [1-4].
2,6-Naphthalene dicarboxylic acid
(2,6-NDA, minimum purity 98%) and ethylene glycol (EG, minimum purity 99%) were purchased from Tokyo Chemicals Industry Co., Ltd.
HFCA should be subsequently converted to FFCA and posteriorly to 2,5-Furan dicarboxylic acid
In addition, only Lambdacyhalothrin persisted and no other metabolites were present (fig 2, table 2).Aneurinibacillus migulanus resulted in the formation of Isopropyl benzene, 1,2,4-Trimethyl benzene, 1,2,4- tris (methylene) cyclohexane, 1- Ethyl-2,4-dimethyl benzene, methyl ester 1,4-Benzene dicarboxylic acid
and 3-Chloro propanic acid (Fig 3, table 2).
With FTIR, they determined that the protective film consists of a complex of the dicarboxylic acid
with [Zn.sup.2+] ions and Zn[(OH).sub.2].
Urea-acetylene dicarboxylic acid
reaction, 10(4): 343-47
