LabJ - Electronic Laboratory Notebook, ELN
[Laboratory Journal for Organic Chemistry Laboratories v. 2.x]
LabJ (a.k.a Electronic Laboratory Notebook, ELN, Laboratory Journal) assists in planning chemical reactions and stores chemical information. It calculates information such as molecular weights, moles, reactant amounts and volumes, percent yields and more. Notes (pocedures, results, references, comments, graphics, etc.) can be attached to the LabJ records. LabJ can be also used to store various data of synthetizing compounds, such as melting and boiling points, spectral data as well as unlimited number of custom fields for your specific needs.
LabJ is realized as an database file for MDL ISIS/BaseTM program. *) Reaction drawings and (sub)structure searches use the ISIS/DrawTM module. *)
Following is a brief overview of the most prominent features of LabJ:
LabJ is a calculations and database program for organic chemists. Chemical reactions can be easily introduced by drawing them in ISIS/Draw module.
LabJ eliminates most of the tedious work of calculating chemical reaction data such as molecular formulas and weights of reactants and products, amounts and volumes of the reactants and yields of products. Calculations are based on graphical reaction and choosed scale, stoichiometry and purity of reagents. Reactants volumes are calculated based on either reagents density or molarity (M [mol/L]).
Because LabJ uses ISIS/Base program as an "database engine" all records can be easily stored and searched. If you want to re-egzamine or scale-up a reaction simply retrieve an existing record, duplicate it, change one of more values (incl. reagents), and everything is recalculated.
All records in a LabJ database are sequenced in numeric order based on reaction number (e.g. KG-1023). Simillary, all products (and fractions) can be logically labelled based on reaction number (e.g. KG-1023-1-3). You can browse throught the database page by page or search for a record by reaction number, reaction scheme, (sub)structure, analytical data, procedure, keywords and much more. This saerch tool generates a list that can be browsed, printed (as separated pages or in tabular form) or saved as a new LabJ database.
LabJ prints records in a form of Reaction Page, Report Page, Tabular Form, and various Analytical Forms (e.g. for IR, MS departments), as well as virtually unlimited number of custom forms for your specific needs.

Current version is: 2.3.4
The ISISTM/Desktop (ISIS/Base nad ISIS/Draw) software package. Please contact MDL Information Systems, Inc. for more information. *)
Currently, you can use LabJ with MDL ISIS/Base 2.x for Microsoft Windows and Apple Macintosh. It is also possible to use LabJ under Unix/Linux with Macintosh or Microsoft Windows emulators, such as Basilisk II, Win4Lin or WINE.
The LabJ is usable for the "chemistry community" free of charge by anybody for any commercial, non-commercial or purely in-house purpose, but it is not yet true GNU GPL program. *) Nevertheless you may adapt the functionality of the program to your local needs and redistribute copies of the package. If you add a valuable feature, or hunt down a bug, you are welcome to contact the author by email and the fix or feature will be most certainly integrated into the official release of LabJ.
However the LabJ package cannot be distributed as part of another program package. Particularly the author strictly forbid the MDL Information Systems, Inc. and its affiliated companies to include the LabJ package as a part of any product. If anybody is interested in providing the LabJ as integrated part of another package, this must be negotiated.
The author assumes no responsibility for errors or malfunctions, or for damages resulting from the use of the programs.

LabJ was originally writen for my own use and a lot of it is messy, so ideas on how to clean it up would be great (cf. Copyright). Please send bug descriptions, suggestions, new LabJ files or succesful stories to firstname.lastname@example.org
- The "Compounds" database was created by Dr. David ElTom (email@example.com ) from the Max-Planck-Institut für Kohlenforschung (Mülheim a.d. Ruhr, Germany) . This database (German version) can be used with LabJ to manage properties of synthesized products
- I acknowledge Dr. Thomas Zoller (firstname.lastname@example.org) and Mr. Jerôme Starck (email@example.com) from Ecole Européenne de Chimie, Polymères et Matériaux, Laboratoire de Synthèse Organique (Strasbourg, France) for many help with developing and testing of the Macintosh version of LabJ.
- I also acknowledge Dr. Szymon Kosinski for many helpful discussions.
