A concise guide for lab scientists on essential queries before ordering research chemicals
When you are planning to order a new research compound, start by confirming the reported purity and the analytical methods used to determine it. Ask the supplier which technique (e.g., HPLC, LC-MS, NMR) was employed, and whether the data reflect the exact batch you will receive.
Request a complete Certificate of Analysis (CoA) for the specific lot. Verify that the CoA includes the batch number, date of analysis, and detailed impurity profile. Knowing the detection limits and acceptance criteria used in the analysis helps you assess suitability for your experiments.
Inquire about the compound’s stability and recommended storage conditions. Ask whether the material is moisture-sensitive, light-sensitive, or requires a specific temperature range. Understanding the shelf-life and any recommended re-conditioning steps can prevent degradation that would affect assay results.
Finally, discuss shipping and safety documentation. Confirm that the supplier provides a Material Safety Data Sheet (MSDS) and that the packaging complies with your institution’s hazardous material policies. Clarify any customs or import restrictions if you are ordering internationally, and ask about the expected delivery timeline to plan your experimental schedule.
