| Packing | TCO-PEG4-NHS ester is supplied in a 25 mg amber glass vial with a tamper-evident cap, labeled with chemical details. |
| Shipping | TCO-PEG4-NHS Ester is shipped in tightly sealed containers under dry, cool conditions, often with ice packs or refrigerated packs to maintain stability. Packaging complies with chemical safety regulations, including appropriate hazard labeling and documentation, to ensure safe, compliant transport from Sigma Aldrich, Merck, or TCI Chemicals. |
| Storage | TCO-PEG4-NHS ester should be stored desiccated at –20°C, protected from light and moisture. The compound is sensitive to hydrolysis; thus, keep the container tightly closed under inert atmosphere if possible. Allow it to reach room temperature before opening to avoid condensation. Use freshly prepared solutions and avoid repeated freeze-thaw cycles to maintain chemical integrity and reactivity. |
