Application
- 4-Aminobenzoic Acid (PABA) in Pharmaceutical Development: Recognized as a valuable biochemical research reagent, 4-aminobenzoic acid is extensively used in the synthesis of various pharmaceutical compounds. Its role as a building block in drug design is crucial for developing new therapeutic agents, particularly in the fields of dermatology and oncology (Clegg and Nichol, 2024).
- UV Protection Research: PABA is renowned for its UV-absorbing properties, making it a key ingredient in sunscreen formulations. Ongoing research evaluates its efficacy and safety, ensuring optimal protection against UV radiation and its potential role in preventing skin cancer (Wang et al., 2024).
- Enzyme Inhibitor Studies: As a nucleoside enzyme inhibitor, 4-aminobenzoic acid is pivotal in biochemical studies that explore the inhibition mechanisms of specific enzymes. These studies are fundamental for understanding disease pathways and developing enzyme-targeted therapies (Buch et al., 2024).
- Vitamin B10 Research: Also known as Vitamin B10, PABA is studied for its role in human nutrition and its therapeutic effects, including in the management of fibrotic skin disorders and hair growth promotion. Research continues to uncover the broader health benefits of this compound (Berto et al., 2024).
- High-Purity PABA for Laboratory Applications: In scientific research, high-purity 4-aminobenzoic acid is essential for conducting precise and controlled experiments, particularly in studies related to its pharmacological properties and its interaction with other biochemical substances in the body (Park et al., 2024).
Other Notes
Ion Mobility: TWCCSN2 value of 133.2 Å2 [M+H]+
The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer.
For a description and overview of how ion mobility enables the measurement of the CCS of an ion visit ims.waters.com.
Further information on the SYNAPT XS mass spectrometer can be found on the IMS microsite and product webpage.
TWCCS measurements are expected to be within 2% of this reference value.
