Catalogue Requirements

Here are the basic guidelines to help you prepare your product catalog for upload to the Molport database. We currently accept catalogs in Microsoft Excel Format, tab delimited text files or SDF files. No matter which format you choose, you need to provide a structure for each compound. We do not accept catalogs with product names or CAS numbers only.


In the Excel table enter the structure as SMILES string. Make sure that you draw the correct isomer of your product. If the product is a mixture or is sold in the salt form, specify all components and ions in the structure field (see example 1, example 2). Do not list in your catalog polymers or other specific products, such as derivative beads or other substrates. Our database does not support such products.

Synonyms Optional Text Separate multiple synonyms with a semicolon. For example: "p-bromobenzaldehyde; 4-bromo-benzaldehyde". Do not add purity or other product specification - such information belongs only in the product name.
CAS_NR Optional Text In Excel, enclose the CAS number in square brackets. For example: [25487-66-5]. Make sure you provide the correct CAS number (e.g. do not enter CAS number of a salt if you are selling a free base). Only one CAS number per structure is acceptable.
