Amendment of the Inventory

This notice is to amend the entry for one substance on the Australian Inventory of Chemical Substances (the Inventory) in accordance with section 20(b) of the Industrial Chemicals (Notification and Assessment) Act 1989.

A chemical with the name 1,1,2,4-Tetramethyl-1-sila-2-aza-6-cyclopentane was nominated without a CAS number and molecular formula during the initial compilation of the Inventory. This name is meaningless as “cyclopentane” is a five-membered ring and therefore has no “6” position, and no substituent was specified after the “6-” locant.

The Director is satisfied that “6-” is a typographical error and the identity of the intended chemical is 1,1,2,4-Tetramethyl-1-sila-2-aza-cyclopentane. Therefore we have amended the inventory listing to add the correct CAS name, CAS number and molecular formula of the substance.
