Look Up Chemical Compound Properties
Identify chemical compounds by name, CAS number, or SMILES string and retrieve molecular weight, formula, and structure data.
Access Chemical Safety Data and Hazard Information
Retrieve safety data sheet information including hazard classifications, handling precautions, and emergency procedures for any chemical.
Quick answer: Use the Chemistry Lookup tool through ToolRouter to access chemical safety data and hazard information directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolWorking with an unfamiliar chemical in a lab, workshop, or industrial setting and not having immediate access to its hazard classification and handling requirements is a genuine safety risk. Safety data sheets (SDS) should be on hand, but they are often outdated, stored in different systems, or simply not available when you need them most.
The safety_data skill returns GHS hazard classifications, signal words, hazard statements, precautionary statements, and first aid measures for any compound. This is the core safety information that determines how a substance should be handled, stored, and disposed of, and what to do in case of exposure.
Lab safety officers building chemical inventories, researchers onboarding new reagents, teachers conducting practical chemistry lessons, and industrial hygienists assessing workplace chemical exposures all use this to access authoritative hazard information on demand.
How to access chemical safety data and hazard information with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude interprets safety data in plain English — explaining what each GHS hazard classification means in practice, what protective equipment is actually required for specific handling scenarios, and what to do in the specific type of exposure or incident you're dealing with. It turns a list of hazard codes into actionable safety guidance.

How to access chemical safety data and hazard information with Claude
Once connected (see setup above), use the Chemistry Lookup tool:
- Ask: "Get safety data for dichloromethane using chemistry-lookup"
- Claude returns GHS classifications, hazard statements, and precautionary measures
- Ask: "What protective equipment do I need to work with this safely?"
- Request: "What should I do if someone inhales the vapour?"
Example prompt for Claude
Try this with Claude using the Chemistry Lookup tool
Get safety data for concentrated sulfuric acid using chemistry-lookup. What are the key hazards, what PPE is required, and what are the first aid steps for skin contact?
Tips for Claude
- Ask Claude to translate GHS hazard codes (H-statements) into plain English
- Request storage compatibility information for chemicals you'll keep near each other
- Ask about disposal requirements alongside handling precautions for a complete safety picture
ChatGPT structures chemical safety data into readable safety briefings, lab procedure notes, and risk assessments. It is well suited to producing training materials that make hazard information accessible to students and non-specialist lab users.

How to access chemical safety data and hazard information with ChatGPT
Once connected (see setup above), use the Chemistry Lookup tool:
- Ask: "Get safety data for acetone using chemistry-lookup"
- ChatGPT returns GHS classification and hazard details
- Request: "Write a safety briefing for students working with this compound"
- Follow up: "What are the key points for a risk assessment?"
Example prompt for ChatGPT
Try this with ChatGPT using the Chemistry Lookup tool
Get safety data for acetone, ethanol, and methanol using chemistry-lookup. Write a comparative safety briefing for a student lab session explaining the key risks and precautions for each.
Tips for ChatGPT
- Ask ChatGPT to draft a COSHH-style risk assessment section from the safety data
- Request a comparison of similar solvents to help choose the safest option for a task
- Ask for the specific P-statements (precautionary measures) most relevant to your use case
Copilot makes GHS hazard data available in your IDE for building laboratory information management systems, chemical inventory applications, and safety compliance tools. The structured hazard classification data maps directly to safety warning displays and compliance check logic.

How to access chemical safety data and hazard information with Copilot
Once connected (see setup above), use the Chemistry Lookup tool:
- In Copilot Chat: "Get safety data for hydrochloric acid using chemistry-lookup"
- Copilot returns structured GHS classification and hazard statement data
- Ask: "Generate a TypeScript interface for the safety data response"
- Request: "Write a function that extracts all H-statements and P-statements from this data"
Example prompt for Copilot
Try this with Copilot using the Chemistry Lookup tool
Fetch safety data for five common lab solvents using chemistry-lookup and return as JSON with compound name, signal word, hazard statements, and key precautionary measures.
Tips for Copilot
- Build a hazard category filter to surface the most critical warnings prominently in your UI
- Use GHS signal word (Danger vs Warning) as a quick severity indicator in chemical inventory lists
- Cache safety data with a long TTL — GHS classifications change infrequently
OpenClaw processes safety data requests for entire chemical inventories in a single batch run, making it suitable for building COSHH registers, regulatory compliance databases, and laboratory safety systems that need current hazard information for every compound on-site.
