733-40-4 Usage

General Description

9,10-Dimethoxyptercarpan is a type of phytoestrogen compound that is found in plants such as Erythrina subumbrans. It has been studied for its potential medicinal properties, including anti-inflammatory and anti-cancer effects. Additionally, it has shown promise in the treatment of osteoporosis due to its ability to stimulate bone formation and inhibit bone resorption. 9,10-Dimethoxyptercarpan…… has also been investigated for its potential use in the development of natural estrogen replacement therapy for postmenopausal women. Overall, 9,10-Dimethoxyptercarpan is a biologically active compound with various potential health benefits and therapeutic applications.

Check Digit Verification of cas no

The CAS Registry Mumber 733-40-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 733-40:
(5*7)+(4*3)+(3*3)+(2*4)+(1*0)=64
64 % 10 = 4
So 733-40-4 is a valid CAS Registry Number.

High-Throughput Screening of Reductive Amination Reactions Using Desorption Electrospray Ionization Mass Spectrometry

Cooks, R. Graham,Ferreira, Christina R.,Li, Yangjie,Logsdon, David L.,Paschoal Sobreira, Tiago Jose,Thompson, David H.

supporting information, p. 1647 - 1657 (2020/10/26)

This study describes the latest generation of a high-throughput screening system that is capable of screening thousands of organic reactions in a single day. This system combines a liquid handling robot with desorption electrospray ionization (DESI) mass spectrometry (MS) for a rapid reaction mixture preparation, accelerated synthesis, and automated MS analysis. A total of 3840 unique reductive amination reactions were screened to demonstrate the throughputs that are capable with the system. Products, byproducts, and intermediates were all monitored in full-scan mass spectra, generating a complete view of the reaction progress. Tandem mass spectrometry experiments were conducted to verify the identity of the products formed. The amine and electrophile reactivity trends represented in the data match what is expected from theory, indicating that the system accurately models the reaction performance. The DESI results correlated well with those generated using more traditional mass spectrometry techniques like liquid chromatography-mass spectrometry, validating the data generated by the system.

A highly active catalyst supported molecular sieves-NaHCO3 mixture for the selective and advantageous N-monoalkylation of amines

Das, Asish R.,Medda, Arunima,Singha, Raghunath,Guchhait, Nikhil

experimental part, p. 841 - 848 (2010/06/01)

Amines are mono-N-alkylated by alkylmesylates in the presence of catalyst supported molecular sieves-NaHCO3 mixture in a regioselective, chemoselective and non-toxic process. Observed chemoselectivity is supported by 'DFT'.

Electrophilic amination with iminomalonate

Niwa, Yasuki,Takayama, Kazuki,Shimizu, Makoto

, p. 5473 - 5476 (2007/10/03)

Diethyl N-anisyliminomalonate has been found to be an excellent electrophilic amination reagent for Grignard reagents to give N-alkylated products in good yields, and subsequent air oxidation affords N-alkylanisidines.
