Buying Guide

Confirm purity and grade

Look for stated purity percentages and labels like USP, FCC, or food/medical grade to match your protocol requirements

Check third-party testing or COA

A certificate of analysis or independent lab test provides verifiable data on impurity levels and consistency

Match solvent type to application

Choose denatured or food-grade ethanol and ethyl alcohol for cleaning or extraction as appropriate, and methylene blue in USP grade for biological assays

Consider bottle size and packaging

Select volume and pack configuration that minimizes contamination risk and fits your expected usage to avoid waste

Mind formulation details

Note alcohol-free, preservative-free, vegan, or food-grade tags when formulation constraints matter for experiments
