Specific details on test material used for the study:
Appearance: white solid crystals
Batch number: S-13(518)
Purity: 98.9% w/w
Key result
ca. 50 °C
Vapour pressure:
ca. 0 Pa

Two measurements with two runs were performed. The calculted vapour pressure was found in a range from 1.76 to 2.26 x10 -4 Pa. With a standard deviation of 0.29 Captan was found to have a vapor pressure of 2.01 x 10 -4 Pa.

At 50°C a vapor pressure of 2.01 x 10-4 Pasacal was determined.

Description of key information

Vapour pressure of captan was determined with gas saturation method to be 2.01 x 10-4 Pascal at 50°C.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
50 °C

Additional information

A vapour pressure of 2.01 x 10 -4 Pa was determined for captan.
