PHYSICAL PROPERTIES 4.1 pH range (MT 75, CIPAC F, p. 205) pH range: 1.5 to 2.0. NOTE 1. Methods available from the Pesticides Information Officer, FAO Plant Production and Protection Division. Ethephon soluble concentrates FAO Specification 373/SL/S/F (1997) 1. DESCRIPTION The material shall consist of a solution of technical ethephon, complying with the requirements of FAO specification 373/TC/S/F (1997), dissolved in suitable solvents and with other necessary added formulants. It shall be a clear or opalescent colourless to tan liquid, free from visible suspended matter and sediment (Note 1). 2. ACTIVE INGREDIENT 2.1 Identity tests (Note 2) An identity test is required if the identity of the active ingredient is in doubt (e.g. gas chromatographic retention time under analytical conditions described in the analysis of mono 2-chloroethyl ester, 2-chloroethyl phosphonic acid: MEPHA). 2.2 Ethephon (373/SL/M/2, CIPAC H, to be published) (Note 2) The ethephon content shall be declared (g/kg or g/l at 20°C, Note 3) and, when determined, the content obtained shall not differ from that declared by more than the following amounts:
3. IMPURITIES 3.1 Manufacturing impurities (Note 2) MEPHA: mono 2-chloroethyl ester, 2-chloroethyl phosphonic acid: Maximum 2 % of the ethephon content found under 2.2. 1,2-dichloroethane: Maximum 0.05 % of the ethephon content found under 2.2. 4. PHYSICAL PROPERTIES 4.1 pH range (MT 75, CIPAC F, p. 205) pH range: 1.5 to 2.0. 4.2 Stability of dilution (MT 41, CIPAC F, p. 131) The product after dilution with CIPAC Standard Water D shall give a clear or opalescent solution at 20°C. After standing for one hour, any visible particles should pass through a 75 m m test sieve. 5.
