Sodium isopropyl xanthate (SIPX), CAS 140-93-2, is a selective sulphide collector with a C3 chain – more selective than SIBX or PAX, and stronger than SEX. It is used in copper and lead-zinc circuits where a cleaner concentrate matters. PolyBlueChem supplies SIPX and the full xanthate range with per-batch COA and SDS.

Basic Information
| CAS number | 140-93-2 |
| Chemical name | Sodium isopropyl xanthate |
| Chain length | C3 (isopropyl) |
| Type | Selective sulphide flotation collector |
Applications
- Copper – selective collector for copper sulphides and for cleaner stages.
- Lead-zinc – collector in lead flotation with zinc depression.
- Selective circuits – where a cleaner concentrate matters more than maximum recovery.
- Blending – often blended with SIBX or PAX to tune the recovery/selectivity balance.
Packaging, storage and documentation
- Moisture-barrier PP/PE bags with inner liner, drums, or jumbo bags.
- Per-batch certificate of analysis (COA) and safety data sheet (SDS).
- Store sealed, cool and dry – xanthates decompose with moisture, heat and time; buy to consumption and rotate stock.
