ACS - Referencing Guide

Safety Data Sheets, Software, Program Code, and Technical Reports and Bulletins.


Safety Data Sheets

The elements to be included in an SDS citation are:

  • The chemical name as the title with all words capitalised,
  • The CAS Registry Number (CAS RN),
  • A manufacturer’s identifier such as a stock, product, or catalog number,
  • The revision or version number,
  • The manufacturer name,
  • Location of manufacturer, and
  • Full date of the last revision of the SDS.
  • If the SDS was obtained from a source other than the manufacturer, include the source name.

Software & Program Code

Software - standalone programs that do not require any special programming environment for their use.

Program code - code modules or scripts that are not included with standard software and are designed to be run as part of a larger programming environment, for example. R, Python, Excel, etc.

Any software or program code used during your research, such as to generate or analyse data, should be referenced.

Technical Reports & Bulletins

Include the report number if there is one, and pagination if applicable.

Italicise the report title, unless it is part of a larger work. If so, the title of the larger work is italicised instead.
