MDEA COA, TDS and SDS: Which Document Do You Need?

A buyer reviewing N-methyldiethanolamine (MDEA, CAS 105-59-9) may receive three documents with the same product name. Each answers a different question. The technical data sheet describes the grade, the certificate of analysis reports results for a specific batch, and the safety data sheet describes hazards and precautions for the product supplied.

Use the TDS to compare grades before ordering

A technical data sheet (TDS) helps you screen a grade against your purchase requirements. A published MDEA TDS, for example, lists assay, water content and color, along with physical properties such as viscosity. Check which entries are specification limits and which are typical values. If a limit matters to your process, have the supplier confirm it in the quotation or purchase specification. www.amines.com

Use the COA to check the lot you receive

A certificate of analysis (COA) reports test results for a specific lot. Match the lot number to the package label, then compare the reported values with your agreed limits. For example, if your purchase order specifies a maximum water content, look for the measured result and its unit on the batch COA. If a shipment contains several lots, confirm that each lot has a corresponding certificate.

Use the SDS to prepare for receiving and handling

A safety data sheet (SDS) gives your safety team information on product identification, hazards, handling, storage and exposure controls. Check that the SDS corresponds to the product and grade being supplied, particularly when the order is for an aqueous solution or a formulated solvent. Share it with the receiving team before the shipment arrives so they can review it against site procedures. Occupational Safety and Health Administration
