This study details a phenolic color developer, C(12)H(10)O(4)S, crucial for leuco colorants. Its molecular structure features perpendicular benzene rings and a 2D hydrogen-bond network, impacting its function.
Area of Science:
- Crystallography
- Materials Science
- Organic Chemistry
Background:
- Phenolic compounds are vital as color developers in various applications.
- Leuco colorants require specific developers to activate their color-changing properties.
- Understanding molecular structure is key to optimizing developer performance.
Purpose of the Study:
- To elucidate the crystal structure and intermolecular interactions of a novel phenolic color developer.
- To investigate the structural basis for the compound's efficacy with leuco colorants.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of hydrogen bonding and dihedral angles provided insights into molecular arrangement.
Main Results:
- The compound C(12)H(10)O(4)S exhibits a unique structure with two nearly perpendicular benzene rings (dihedral angle = 91.5°).
- Intermolecular O-H⋯O hydrogen bonds form between hydroxyl groups and sulfonyl oxygen atoms.
- A two-dimensional hydrogen-bond network is established through interactions with four symmetry-related molecules.
Conclusions:
- The determined crystal structure provides a foundation for understanding the compound's role as a phenolic color developer.
- The observed hydrogen-bonding network likely influences the stability and reactivity of the developer in leuco colorant systems.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
