The fused heterocyclic formed by fusion of pyrimidine and pyrrole rings, is a solid compound with a chromatographic purity of 98%.
It displays keto and enol isomers as is reflected in its synonyms and is an important biochemical reagent and a vital nucleobase.
The bi-naphthol moiety is a colorless solid. The structure depicts two naphthol rings joined at the respective 1-positions. The presence of two hydroxy groups renders the molecule highly reactive and the product forms a backbone of a variety of value-added chemicals and ligands.
Over the last year, several drugs have either been developed or tested to treat coronavirus. Now there’s another new antiviral drug that’s showing some promise by demonstrating ability to stop SARS-CoV-2 transmission within 24 hour!
Looking within a short-term horizon, the outlook for container shipping over the next 2-3 months appears relatively well-known, although certainly not well-liked by shippers. In essence, we will continue to see a situation of bottleneck problems, capacity shortages and high pressure on rates. This is, hopefully, not a surprise to anyone now.
An efficient, versatile linker is developed for the synthesis of C-terminal primary/secondary amides and hydrazides as well as peptide alcohols, which is compatible with solid-phase peptide synthesis (SPPS) and suppresses side reactions. It is termed as Ramage Linker.
Carbon dioxide (CO2) is one of the major greenhouse gases causing global warming. If carbon dioxide could be converted into energy, it would be killing two birds with one stone in addressing the environmental issues. A new photocatalyst is developed recently, which can produce methane fuel (CH4) selectively and effectively from carbon dioxide using sunlight. According to this research, the quantity of methane produced was almost doubled in the first 8 hours of the reaction process.
Reliable temperature-controlled coronavirus vaccine logistics require smooth integration of all those involved as well as materials that provide good insulation. As the range of coronavirus vaccines grows, so do the requirements for their distribution. The different vaccines need to be stored and transported at different temperature ranges – often together in the same vehicle or cold store. Handling complex processes like this is routine for leading logistics companies. But they depend on the skills of packaging providers and raw materials suppliers.
To control Covid-19 in a more effective way, leading face mask manufacturers have adopted technologies like Virus Protection Technology (VPT) approved by regulatory authorities globally to ensure maximum breathability while ensuring protection through anti-viral and anti-bacterial coating.

Before the COVID-19 pandemic,
almost all audits and inspections were conducted on site. Plant audits were performed based on the Pre- Audit questionnaires (PAQ), audit agendas and checklists assigned by the auditor which were more or less a supplement to the overall onsite supplier qualification process of GMP audits.
