The crystal structure of C8H9NO3 reveals hydrogen bonds forming dimers and undulating layers. An intramolecular hydrogen bond also exists within the primary amide group.
Area of Science:
- Crystallography
- Molecular structure
- Supramolecular chemistry
Background:
- Understanding the intermolecular forces governing crystal packing is crucial for predicting material properties.
- Hydrogen bonding plays a significant role in the self-assembly of organic molecules.
Purpose of the Study:
- To elucidate the crystal structure of C8H9NO3.
- To investigate the hydrogen bonding network and molecular arrangement in the solid state.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the crystal structure.
- Analysis of intermolecular and intramolecular interactions was performed.
Main Results:
- The crystal structure of C8H9NO3 exhibits centrosymmetric dimers linked by N-H⋯O hydrogen bonds.
- These dimers form undulating hydrogen-bonded layers parallel to the [101] plane via O-H⋯O interactions.
- An intramolecular hydrogen bond was observed between the amide N-H and the methoxy O atom.
Conclusions:
- The crystal packing of C8H9NO3 is dominated by a combination of intermolecular and intramolecular hydrogen bonding.
- The identified hydrogen bonding motifs dictate the formation of layered supramolecular structures.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
