PG5 has a molecular mass of about 200 MDa or 200,000,000 g/mol. It has roughly 20 million atoms and a diameter of roughly 10 nm. Its length is up to a few micrometers. [3] It is similar in size to a tobacco mosaic virus with comparable length and diameter. PG5 was shown to be resistant against attempts to flatten its structure.
Screenshot of the CAS Common Chemistry database with information about caffeine ().. A CAS Registry Number [1] (also referred to as CAS RN [2] or informally CAS Number) is a unique identification number, assigned by the Chemical Abstracts Service (CAS) in the US to every chemical substance described in the open scientific literature, in order to index the substance in the CAS Registry.
As of August 2018, PubChem contains 247.3 million substance descriptions, 96.5 million unique chemical structures, contributed by 629 data sources from 40 countries. It also contains 237 million bioactivity test results from 1.25 million biological assays, covering >10,000 target protein sequences.
This is unlike phosphorus pentachloride which exists as neutral PCl 5 molecules in the gas and liquid states but adopts the ionic form [PCl 4] + [PCl 6] − (tetrachlorophosphonium hexachlorophosphate(V)) in the solid state. The average bond lengths in the crystal structure of POCl 3 are 1.98 Å for P–Cl and 1.46 Å for P=O. [5]
