BBC News (7 May 2021) reported that India has begun distributing a new locally developed drug to treat Covid-19 symptoms.
Authorities have approved 2-DG and it is to be first used in hospitals across the capital, Delhi. According to a government statement, it “will be of immense benefit to the people suffering” from Covid-19.

2-DG or 2-Deoxy-D-glucose is a glucose molecule which has the 2-hydroxyl group replaced by hydrogen, and it is not metabolized by glycolysis. D-Glucal is the starting material for the synthesizing of 2-Deoxy-D-glucose. The separation of 2-Deoxy-D-glucose, D-Glucal and glucose was made by Shodex HILICpak VG-50 4E column which is a polymer-based amino column.

Sample : 10 µL
0.15 %(w/v) each in H2O/CH3CN=5/5
1. D-Glucal
2. 2-Deoxy-D-glucose
3. Glucose

Column : Shodex HILICpak VG-50 4E (4.6 mm I.D. x 250 mm)
Eluent : H2O/CH3CN=12/88
Flow rate : 1.0 mL/min
Detector : RI
Column temp. : 40 ℃

Showa Denko Group contributes to social responsibility by ensuring a stable supply and increasing Chloroprene latex supply to the medical glove market.

The demand of medical examination gloves increases drastically during COVID-19 pandemic. This is much higher than before COVID-19 pandemic.  

Synthetic rubber, Nitrile butadiene rubber (NBR) is commonly known as major raw material for medical examination gloves, however, the glove makers are starting to enquire our Showa Denko Chloroprene latex to produce high-quality gloves. 

As the world-leading Chloroprene latex supplier for medical glove makers, Showa Denko has been supplying to the medical gloves market for a long time. And, we are fully operational with all its activities related to production, warehousing, and shipping of Showa Denko Chloroprene latex to ensure the stable supply of Showa Denko Chloroprene latex during Covid-19 pandemic. This is a part of our contribution to social responsibility.

If you considered developing a new product with Showa Denko Chloroprene, we could ensure that our product could meet your expectations at the same time our team is ready to assist you to solve the technical issue with our long time accumulated experience and knowledge.

New glove makers are blooming during this demanding season, and consumers would buy whatever gloves that are supplying in the market because of limited supply. However, consumers would start to choose the best gloves when the Covid-19 pandemic was over, or when the supply was greater than demand. Besides price concern, the performance of the glove is equally important, and this is differentiating you from your competitors (NBR glove makers). Chloroprene glove could be your choice to build a competitive advantage. The quality of chloroprene gloves is better than NBR gloves in the viewpoint of softness and chemical resistance.
