CompTox Mobile vs Japality Primer

Find chemical structure instantly by exact mass (m/z), ¹³C NMR chemical shifts, structure name or CAS Registry Number in a database of about 720,000 EPA CompTox structures. The Chemistry Dashboard is part of a suite of dashboards developed by EPA to help evaluate the safety of chemicals. The Chemistry Dashboard provides access to a variety of information on over 720,000 chemicals. Within the Chemistry Dashboard, users can access chemical structures, experimental and predicted physicochemical and toxicity data, and additional links to relevant websites and applications. It maps curated physicochemical property data associated with chemical substances to their corresponding chemical structures. This data are compiled from sources including the EPA’s computational toxicology research databases, and public domain databases such as the National Center for Biotechnology Information’s PubChem database.

Japality Primer helps you design PCR primer pairs directly on iPhone and iPad. Paste a DNA sequence or FASTA input, review core sequence metrics, and generate ranked primer candidates with adjustable design constraints. The app is built for fast iteration in molecular biology and bioinformatics workflows. Features: • Paste raw DNA or FASTA sequence input • Automatic sequence cleanup and validation • View sequence length, GC content, approximate melting temperature, and reverse complement • Design local PCR primer pairs on device • Adjust target Tm, product size range, primer length range, and number of returned pairs • Review ranked primer candidates with quality scoring • Use offline demo sequences for quick testing Japality Primer is intended as a research and productivity tool for primer exploration. Results should be reviewed and validated experimentally before laboratory or publication use.
