Description of key information

The classification is made because Carbon disulphide and Pentan-1-ol/Amyl alcohol  are both reagents used in the manufacture of S-allyl O-pentyl dithiocarbonate which are flammable.

Carbon disulphide (CAS number 75–15–0)  is both reagents used in the manufacture of S-allyl O-pentyl dithiocarbonate. Therefore, Carbon disulphide (CAS number 75–15–0) need to be considered in the assessment of S-allyl O-pentyl dithiocarbonate. CS2 is flammable in a range between 1.3 and 50 % (v/v) in air.

Pentan-1-ol/Amyl alcohol   is flammable in a range between 1.2 and 10 % (v/v) in air. Pentan-1-ol/Amyl alcohol  is both reagents used in the manufacture of S-allyl O-pentyl dithiocarbonate. Therefore, pentan-1-ol/Amyl alcohol need to be considered in the assessment of S-allyl O-pentyl dithiocarbonate.
