Download the list in CSV format (encoded in UTF-8):

The CSV is a delimited data format that has fields/columns separated by the semicolon character and records/rows separated by newlines. Fields that may contain a special character (semicolon, newline, or double quote), are enclosed in double quotes

For an easier handling, the list of Pre-registered substances is available in four parts ordered by EC number. They contain the same information as the following full list.

PRS List in CSV, part 1/4 (3.5MB), EC Numbers from 200-001-8 to 249-999-7
PRS List in CSV, part 2/4 (4.7MB), EC Numbers from 250-000-1 to 299-999-6
