Chemical Lookup

Chemical Lookup ({chemlook}) is a database and repository containing tabular information on chemicals, such as names, identifiers (e.g. CAS, InChI) as well as identifiers to other databases (e.g. Pubchem CID).

Usage

You can use the R-package {chemlook} to query the database directly from R OR you can download the data from its Zenodo-Repository.

From R

Installation

remotes::install_github('andschar/chemlook')

Example

You can query the database by different identifiers. For a detailed list see ?chemlook::cl_query(). Some examples are shown below.

require(chemlook)

cl_query('1071-83-6', from = 'cas')
cl_query('WSFSSNUMVMOOMR-UHFFFAOYSA-N', from = 'inchikey')
cl_query('DTXSID8020961', from = 'dtxsid')

Raw Data only

All the data tables are stored on the Zenodo-Respository as a SQLite file.

table	description
cl_class	Containing chemical classification information
cl_id	Table of identifiers

The tables can be merged via the unique key column cl_id.
