What should an inquiry include?

Names, CAS, grade (AR/BR/USP/cell culture/molecular biology), pack size, use, sterile or low-endotoxin needs and the lead time you need.

What are COA and MSDS?

The COA is the batch test report; MSDS/SDS is the safety data sheet. Both follow the supplier batch.

For research or industrial use only. Not for human or animal diagnosis or treatment, and not for drug or food use. Grade, pack size and lead time follow the supplier batch COA / SDS. Figures on this site are general industry references, not a factory specification.
