1196-92-5 Usage

Uses

4-Hydroxy-3-methoxybenzylamine is used in preparation of capsaicin.

Check Digit Verification of cas no

The CAS Registry Mumber 1196-92-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1196-92:
(6*1)+(5*1)+(4*9)+(3*6)+(2*9)+(1*2)=85
85 % 10 = 5
So 1196-92-5 is a valid CAS Registry Number.

Facile synthesis and promising antibacterial properties of a new guaiacol-based polymer

Liu, Hefang,Lepoittevin, Bénédicte,Roddier, Céline,Guerineau, Vincent,Bech, Lo?c,Herry, Jean-Marie,Bellon-Fontaine, Marie-Noelle,Roger, Philippe

, p. 1908 - 1916 (2011)

A new acrylamide-type monomer (N-(4-hydroxy-3-methoxy-benzyl)-acrylamide) derived from guaiacol was successfully synthesized. Polymers containing guaiacol moiety were obtained via conventional radical polymerization of this monomer with AIBN as initiator. The influence of reaction time, initiator concentration and temperature on polymers characteristics was studied. Evaluation of the termination mode in free-radical polymerization was performed by MALDI-TOF mass spectrometry. Termination occurs mainly by disproportionation reaction. Additional peaks in the spectrum were attributed to side chain reactions implying phenoxy radicals. This new polymer exhibits a potential antibacterial activity against Bacillus subtilis by using anti-adhesion and anti-biofilm tests. After an adhesion time of 3 h, compared to a non-coated glass slide, there was a decrease of bacteria of 99% on the polymer coated glass slide. After three days of culture in a bacterial suspension, no biofilm was observed on the polymer coated surface.

Paragraph 0009, (2021/06/26)

The invention relates to a capsaicin preparation method and capsaicin prepared by the method. The preparation method comprises the steps that: in the presence of an organic solvent and a catalyst, vanillylamine and carboxylic acid serve as reactants, after amidation reaction, capsaicin reaction liquid is obtained, and the catalyst comprises a boric acid ester compound. Compared with the prior art, the capsaicin preparation method provided by the invention has the following beneficial effects: 1) a large amount of water is not generated in the reaction process, violent reflux for water separation is not needed, the production cost is reduced, and the production safety is improved; 2) boric acid is replaced by the boric acid ester compound, so that the reaction time can be shortened, the reaction yield can be improved, and the product purity is very high; and 3) the boric acid ester compound can be recycled after proper treatment after the reaction, so that the production cost is saved, and green production is realized.

Paragraph 0115-0117, (2021/04/07)

The invention provides a preparation method of capsaicine and capsaicine prepared by the method. The preparation method comprises the following steps: in the presence of an organic solvent and a catalyst, by taking vanillylamine carboxylate and carboxylic acid as reactants, carrying out amidation reaction to obtain a capsaicine reaction liquid. Compared with the prior art, the capsaicine preparation method provided by the invention at least has one of the following beneficial effects: 1) vanillylamine is converted into vanillylamine carboxylate, so that the problem of oxidative discoloration of vanillylamine is avoided, and the problems of purification, drying and storage of intermediate products are solved; 2) the vanillylamine carboxylate can be directly used for the next amidation reaction, other substances are not introduced, and the amidation reaction, operation and post-treatment are not influenced; and 3) after the vanillylamine solid is salified and dissolved, the thorough separation of the Raney Ni catalyst is facilitated, and the catalyst separated by the method can be continuously used after being treated.

Facile synthesis of controllable graphene-co-shelled reusable Ni/NiO nanoparticles and their application in the synthesis of amines under mild conditions

The primary objective of many researchers in chemical synthesis is the development of recyclable and easily accessible catalysts. These catalysts should preferably be made from Earth-abundant metals and have the ability to be utilised in the synthesis of pharmaceutically important compounds. Amines are classified as privileged compounds, and are used extensively in the fine and bulk chemical industries, as well as in pharmaceutical and materials research. In many laboratories and in industry, transition metal catalysed reductive amination of carbonyl compounds is performed using predominantly ammonia and H2. However, these reactions usually require precious metal-based catalysts or RANEY nickel, and require harsh reaction conditions and yield low selectivity for the desired products. Herein, we describe a simple and environmentally friendly method for the preparation of thin graphene spheres that encapsulate uniform Ni/NiO nanoalloy catalysts (Ni/NiO?C) using nickel citrate as the precursor. The resulting catalysts are stable and reusable and were successfully used for the synthesis of primary, secondary, tertiary, and N-methylamines (more than 62 examples). The reaction couples easily accessible carbonyl compounds (aldehydes and ketones) with ammonia, amines, and H2 under very mild industrially viable and scalable conditions (80 °C and 1 MPa H2 pressure, 4 h), offering cost-effective access to numerous functionalized, structurally diverse linear and branched benzylic, heterocyclic, and aliphatic amines including drugs and steroid derivatives. We have also demonstrated the scale-up of the heterogeneous amination protocol to gram-scale synthesis. Furthermore, the catalyst can be immobilized on a magnetic stirring bar and be conveniently recycled up to five times without any significant loss of catalytic activity and selectivity for the product.
