Description
Identity
The certificate values that define this material.
- Molecular formula C12H14N2O2, formula weight 218.25 g/mol.
- CAS registry number 77472-70-9.
- Systematic name 2-(2-oxo-4-phenylpyrrolidin-1-yl)acetamide.
- Common synonym Carphedon; both names appear across supplier documentation.
Scaffold
The molecule is piracetam with a phenyl ring added at position four of the lactam ring.
- Core is a 2-oxopyrrolidine, a gamma-lactam, bearing an acetamide arm on nitrogen.
- The 4-phenyl group raises lipophilicity sharply against the unsubstituted parent.
- Added aromaticity supplies a usable ultraviolet chromophore, unlike the plain racetams.
- Both amide functions are neutral; there is no ionisable centre in an ordinary buffer range.
Stereochemistry
Ring position four carries both a hydrogen and a phenyl group, which makes it a stereocentre.
- Two enantiomers exist, conventionally designated R and S.
- Material is racemic unless the specification states an enantiomeric ratio.
- Chiral chromatography, not an achiral purity figure, is what tells them apart.
- A specific rotation entry means nothing without the solvent and concentration used.
Figures that circulate and should not be trusted
Secondary web sources carry physical constants for this compound that contradict one another by a wide margin.
- Melting and boiling figures found online are frequently computed predictions, not measurements.
- Only the value on the batch certificate of analysis belongs in a laboratory record.
- Where a constant genuinely matters, measure it in house and record the method used.
Storage and handling
Nothing exotic is required, though the crystalline habit adds one practical concern.
- Sealed container, dry, cool, protected from direct light.
- Let the container reach room temperature before opening, to avoid condensation.
- Fine crystalline powder: weigh under extraction and avoid raising airborne dust.
- Keep desiccant in the outer packaging and renew it on a schedule.
Analytical route
The phenyl ring makes routine analytical work easier here than with other racetams.
- Liquid chromatography with ultraviolet detection is adequate for purity by area percent.
- Proton nuclear magnetic resonance against a reference spectrum confirms identity quickly.
- Mass spectrometry confirms the molecular mass and flags des-phenyl impurities.
- Residual solvent by headspace gas chromatography completes a basic incoming check.
