Description
What follows is a parameter sheet rather than a description. The left column is what the certificate states, the middle column is the value itself, and the right column is what that value changes about handling the material at the bench.
| Parameter | Value | Consequence in the laboratory |
|---|---|---|
| CAS registry number | 68497-62-1 | The only unambiguous identifier when ordering, when retrieving a safety data sheet, and when separating the free base from any salt form in a records system. |
| Molecular formula | C14H27N3O2 | Three nitrogens and no aromatic ring. Ultraviolet absorbance is weak, so a purity assay leaning on a diode array detector will under-report what is actually present. |
| Formula weight | 269.38 g/mol | The figure behind every molar calculation. A salt form carries a different mass and a different registry number, so the two must never be swapped in a calculation sheet. |
| Core scaffold | 2-oxopyrrolidin-1-yl acetamide | Places the compound in the racetam family and predicts its chemistry: a stable five-membered lactam ring with an acetamide arm on the ring nitrogen. |
| Amide substituent | N-[2-(diisopropylamino)ethyl] | A basic tertiary amine on the side chain. It forms salts with acids, raises affinity for atmospheric moisture and carbon dioxide, and offers a handle for ion-pairing chromatography. |
| Physical form | As stated on the batch certificate | Free base and salt forms of this compound do not present identically. The certificate, not a catalogue line, defines what is in the container. |
| Stereochemistry | No stereocentre in the scaffold | Nothing to resolve and no optical rotation specification, which makes identity testing simpler than for racetams bearing a substituted ring carbon. |
The basic amine in the side chain is the single feature that most changes day-to-day handling. Bases of this kind pull water and carbon dioxide from laboratory air, and a container left open on a bench gains mass measurably faster than a neutral amide would. Weighing is done quickly, from a container already equilibrated to room temperature, and the master lot is resealed immediately afterwards. See also our reagent-grade material: L-Tyrosin / L-Tyrosin /Tyrosin Reinheit ≥ 99% 1000.
Analytically, the absence of a strong chromophore is the constraint worth planning around. Purity by area percent on a diode array detector flatters the material, because impurities may absorb strongly where the main component barely absorbs at all. Charged aerosol or evaporative light scattering detection, or coupling to a mass spectrometer, gives a fairer picture, while proton nuclear magnetic resonance against a reference spectrum remains the fastest identity confirmation. See also our laboratory reagent: L-Tyrosine / L-Tyrosine /Tyrosine Purity ≥ 99% 100.
Storage follows from the same chemistry: sealed, dry, cool, protected from light, with the desiccant renewed rather than assumed active. Where a lot will be sampled repeatedly over months, splitting it into single-use portions at intake costs a few minutes and removes the repeated humidity exposure that ruins the last portion of an otherwise sound batch.
