Basic Information and Molecular Structure

CAS Number: The standard registration number is 607-66-9 (registration information is consistent across different chemical databases and serves as a unique identifier for the substance).

Molecular Formula and Molecular Weight:

Molecular Formula: C₉H₇NO₂

Molecular Weight: 161.16 g/mol (calculated based on atomic weights: C=12.01, H=1.008, N=14.01, O=16.00).

Core Molecular Structure:

The quinoline ring (nitrogen atom at position 1, benzene ring fused to pyridine ring) serves as the parent nucleus. Key substitution sites are:

A hydroxyl group (-OH) is attached at position 4 (on the pyridine ring) and position 8 (on the benzene ring).

The presence of the hydroxyl group enhances the molecule's polarity and hydrogen bonding ability. It also serves as a reactive functional group capable of participating in reactions such as acylation, etherification, and condensation. The conjugated structure of the quinoline ring imparts certain optical properties (such as UV absorption and fluorescence).
