How do you cite the PubChem compound database?

To cite an original source of PubChem data use one of the following:

  1. Refer to attribution on the PubChem record.
  2. Cite publication linked to record, if present.
  3. Navigate to the source using our PubChem Data Sources page.

What is CID and SID in lab report?

The primary identifiers for the Substance, Compound and BioAssay databases are SID (SubstanceID), CID (CompoundID) and AID (AssayID), respectively. Figure 1. Data organization in PubChem. SID, CID and AID are the identifiers for the Substance, Compound and BioAssay databases, respectively.

What is PubChem used for?

PubChem is an open chemistry database at the National Institutes of Health (NIH). “Open” means that you can put your scientific data in PubChem and that others may use it. Since the launch in 2004, PubChem has become a key chemical information resource for scientists, students, and the general public.

Is PubChem a database?

PubChem (PubChem Project) is a database system of small molecules and, for a subset of them, of biological activity data measured in a variety of assays.

What’s the difference between compound and substance?

PubChem users sometimes ask about the difference between a substance and a compound. In PubChem terminology, a substance is a chemical sample description provided by a single source and a compound is a normalized chemical structure representation found in one or more contributed substances.

How do you find the chemical compound?

To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound.

How do you identify chemical structures?

Concerning chemical structure one has to distinguish between pure connectivity of the atoms within a molecule (chemical constitution), a description of a three-dimensional arrangement (molecular configuration, includes e.g. information on chirality) and the precise determination of bond lengths, angles and torsion …

What is the common name for H2O?

What is the correct name for SeF6?

Selenium hexafluoride | SeF6 – PubChem.

Which substance is present in large amount?

The substance that is present in the largest amount is called the solvent and the one present in the smaller amount is called a solute.

Which is not a mixture?

Water i.e. H2O, is a pure substance or a compound which is made up of hydrogen and oxygen. A mixture would be a water with other things dissolved in it. Hence, distilled water is not a mixture.

How to get a CID from a Pubchem CID?

At IU I maintain a partial mirror of PubChem, which stores the compound, substance, association and synonym data (and a partial dump of the bioassay data) in a PostgreSQL database, updated on a monthly schedule. For this problem, the synonym table contains two columns – CID and synonyms associated with a CID.

How to search for a chemical formula in PubChem?

Users may also specify the structural query input by PubChem Compound Identifier (CID), SMILES , SMARTS , InChI , Molecular Formula , or by upload of a supported structure file format . To perform a chemical structure search you must provide an appropriate query.

How to use PubChem identifier Exchange Web service?

This document describes how to use the PubChem Identifier Exchange web service, which can be found at the URL: The input IDs are converted into CIDs, which is called input CIDs. The CIDs that satisfy the condition specified by the selected operation type are retrieved.

How are input IDs converted to output CIDs?

The input IDs are converted into CIDs, which is called input CIDs. The CIDs that satisfy the condition specified by the selected operation type are retrieved. We called these CIDs, output CIDs.
