576-36-3 Usage

Uses

D-Galactonic Acid is a sugar acid that is a metabolic breakdown product of galactose.

Purification Methods

Crystallise D-galactonic acid from EtOH or aqueous EtOH. It cyclises to D-galactono-1,4-lactone, m 134-136o, and mutarotates in 1hour to [] 546 -92o (c 5, H2O). It can also be obtained from the Na salt by adding 10times its weight of acetic acid, warming till just brown, cooling, filtering off the crystals and drying them. It has m 145-146o, [ ] D –13.6o (c 1, H2O, 2minutes and mutarotates to – 5 7 . 6o). [Blackburn & Upson J Am Chem Soc 55 2514 1933, Beilstein 3 IV 1257, and for the -lactone see below.]

Check Digit Verification of cas no

The CAS Registry Mumber 576-36-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,7 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 576-36:
(5*5)+(4*7)+(3*6)+(2*3)+(1*6)=83
83 % 10 = 3
So 576-36-3 is a valid CAS Registry Number.

Preparation method of gluconic acid

-

Paragraph 0009; 0021; 0024-0059, (2019/06/05)

The invention discloses a method for preparing gluconic acid from glucose as a raw material with a catalytic oxidation means. Gluconic acid is prepared through oxidation of glucose by an aqueous phasewith air or oxygen as an oxidizing agent and a transition metal compound and nitrous acid or nitrite as a composite catalyst. The reaction is simple in operation and mild in condition, the glucose conversion rate is high, the selectivity of the gluconic acid product is good, and the method has important application prospects.

Aqueous oxidation of sugars into sugar acids using hydrotalcite-supported gold nanoparticle catalyst under atmospheric molecular oxygen

Tomar, Ravi,Sharma, Jatin,Nishimura, Shun,Ebitani, Kohki

supporting information, p. 843 - 845 (2016/07/16)

Hydrotalcite-supported gold nanoparticles show good activity as a heterogeneous catalyst for the oxidation of monosaccharides (xylose, ribose, galactose and mannose) and disaccharides (lactose and cellobiose) into the corresponding sugar acids under external base-free conditions in water solvent using atmospheric pressure of molecular oxygen. The produced sugar acids were thoroughly identified by 1H-, 13C-, and HMQC-NMR and ESI-FT-ICR MS spectroscopic techniques.

Hydroxyl radical-induced etching of glutathione-capped gold nanoparticles to oligomeric AuI-thiolate complexes

Chen, Tzu-Heng,Nieh, Chih-Chun,Shih, Ya-Chen,Ke, Chen-Yi,Tseng, Wei-Lung

, p. 45158 - 45164 (2015/06/02)

Thiol-induced core etching of gold nanoparticles is a general method for the production of gold nanoclusters (AuNCs) of various sizes. This paper is the first report on the efficient reaction of glutathione-capped gold nanoparticles (GSH-AuNPs) with hydroxyl radicals to produce oligomeric AuI-thiolate complexes at ambient temperature. Also, hydroxyl radicals can etch commercially available gold nanoparticles (100 nm); this strategy can be applied for the removal of gold from scrap electronics. Additionally, proteins can trigger the aggregation of oligomeric AuI-thiolate complexes under neutral conditions resulting in the formation of fluorescent AuNCs. For example, the reaction of trypsin, lysozyme, and glucose oxidase with oligomeric AuI-thiolate complexes produces Au5, Au8, and Au13 clusters with emission maxima at 415, 460, and 535 nm, respectively. Interestingly, trypsin- and glucose oxidase-stabilized AuNCs could sense GSH and glucose via GSH-induced etching of AuNCs and H2O2-mediated oxidation of AuNCs, respectively. This journal is
