The specification sheet of a 1 g unit of omberacetam holds around eight lines, and each of them implies a handling decision. Read as a table with a third column, the sheet stops being a formality and becomes a short list of instructions for the store and the bench.<\/p>\n\n\n\n

Parameter<\/th>Value<\/th>What follows in the laboratory<\/th><\/tr><\/thead>
Registry number<\/td>157115-85-0<\/td>The identifier for orders, register entries and waste papers. Catalogue synonyms circulate widely, so the number is what keeps two deliveries comparable.<\/td><\/tr>
International non-proprietary name<\/td>omberacetam<\/td>Databases increasingly index the compound under this name, so a literature search on the brand name alone returns an incomplete set.<\/td><\/tr>
Molecular formula<\/td>C17H22N2O4<\/td>Confirms the ethyl ester of a phenylacetyl prolylglycine skeleton, which puts an ester group at the centre of every stability consideration.<\/td><\/tr>
Molecular weight<\/td>318.37<\/td>Basis for converting weighed mass into molar concentration for a working solution.<\/td><\/tr>
Melting range<\/td>94.0 to 98.0 degrees Celsius per supplier technical sheets<\/td>A narrow observed range supports identity. A range that is broader or lower than declared points to moisture or to an impurity and is grounds for questioning the lot.<\/td><\/tr>

The ester group is the parameter that quietly governs shelf life. Esters hydrolyse in the presence of water, and the products of that hydrolysis are a free acid and ethanol, neither of which shows up as a dramatic change in appearance. Keeping the container dry and closed is therefore not general laboratory hygiene but a specific stability measure for this structure.<\/p>\n\n\n\n

The proline residue makes stereochemistry a second parameter worth asking about. A certificate that reports only a chromatographic assay under achiral conditions says nothing about configuration at that centre, and for comparative work the chiral line is the one that makes two lots equivalent. Requesting it at the point of order costs nothing; reconstructing it afterwards costs a method development cycle.

Everything else is routine store practice. The container is equilibrated before opening so that condensation stays off the powder, the withdrawal is logged with date, mass and initials, and the certificate is archived together with the chromatogram that supports it. When the jar is finished, the paperwork stays as long as the results derived from that batch remain in circulation.
