An equivalent match in Quartzy is a scientifically vetted alternative. Here is an example of how an equivalent chemical might be offered to you through Quartzy's Effortless Quotes Program.

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 Amresco Chem-Impex Caisson Labs
Catalog # 0404-1KG 00835 S018-1KG
Description Sodium Phosphate, Dibasic, Anhydrous Sodium phosphate dibasic, anhydrous Sodium Phosphate, Dibasic, Anhydrous

Purity ≥99% ≥99% ≥99%
Quantity 1 kg 1 kg 1 kg
Price $55.13 $40.00 $33.85


As you can see, CAS, purity, and quantity all match up. The only variance here is the manufacturer and the price!
