Common Name:Propineb

CAS Number: 12071-83-9

Chemical Name (IUPAC): polymeric zinc propylenebis(dithiocarbamate)

Description: the material shall consist of propineb together with related manufacturing impurities and shall be a white powder, free from visible extraneous matter and added modifying agents other than the added stabilisers and manufacturing aids.

Identity test: identity of the active constituent must be established by one or more of the following methods: spectroscopic tests (IR spectrum, NMR, mass spectra), Chromatography (HPLC or GC retention time with reference compound) or any other suitable test method.

Composition: Propineb active constituent is unstable and the stabiliser (hexamethylene tetramine) and processing aids are added; also active constituent is not isolated, the formulated product is produced in a continuous process.

Active constituent: 800 g/kg minimum.

Toxicological Impurity: propylene thiourea 5g /kg maximum; arsenic: 25 mg/kg maximum

Analytical methods:

The analytical method used for the determination of the active constituent and toxicological significant impurities must be validated in accordance with the APVMA guidelines for the validation of analytical methods.

Collaboratively tested standard CIPAC and AOAC methods for the analysis for the active constituent and any method submitted as a part of the new active constituent application that has been accepted by the APVMA are regarded as validated and do not require revalidation.

Unless the scope of the collaborative method (CIPAC and AOAC) also includes toxicological significant impurities in the active constituent, validation data for impurities are required
