For chemicals, Quartzy’s science team is matching CAS #, purity, volume, grade, and application while also comparing pricing to find the best alternative for your lab.
Here’s an example of a chemical match:
| Manufacturer | VWR | Chem-Impex | Caisson Labs |
| Catalog # | 0404-1KG | 00835 | S018-1KG |
| Description | Sodium Phosphate, Dibasic, Anhydrous | Sodium phosphate dibasic, anhydrous | Sodium Phosphate, Dibasic, Anhydrous |
| CAS # | 7558-79-4 | 7558-79-4 | 7558-79-4 |
| Purity | ≥99% | ≥99% | ≥99% |
| Grade | ACS | ACS | ACS |
| Quantity | 1 kg | 1 kg | 1 kg |
As you can see, CAS, purity, and quantity all match up. The only variance here is the manufacturer and the price!
