Make confident chemical decisions, before they become compliance problems.
Chemsana evaluates SDS data, inventory totals, and 3,700+ regulations in real time, so your site knows what’s allowed, what needs reporting, and what’s blocked — before you buy, store, or use it.
SDS sheets tell you composition. They don’t tell you what to do.
Industrial sites still make chemical decisions in spreadsheets, then learn about the consequences months later.
- ✕Regulatory thresholds apply at the site-wide aggregated level, not per product.
- ✕Mixtures obscure the true CAS-level totals across your inventory.
- ✕Unit conversions (gal → lb) are unreliable when density varies by product.
- ✕EPA, OSHA, and RCRA all impose different rules — and overlap.
- ✕Air permitting introduces lead times measured in months or years.
- ✕No tools support forward-looking, “what if” compliance analysis.
From SDS to a defensible decision in seconds.
Ingest the SDS
Drop in a safety data sheet. Our extraction engine pulls CAS numbers, composition, and density — mixtures included.
Aggregate inventory
Connect via API, upload CSV, or enter manually. Chemsana rolls up CAS-level totals across every product on site.
Get a decision
Allowed, requires reporting, or blocked — with regulatory citations, threshold math, and an audit trail.
Real product. Real decisions. Real citations.
No vapor-ware screenshots. Every view shown here is the live workflow your team will use on day one.
Drop in an SDS. Get a clean composition.
Upload a PDF and the extraction engine pulls CAS numbers, concentration ranges, and physical properties from Sections 1, 3, and 9 — then refines the linked product’s composition automatically.
- Mixtures, blends, and synonyms handled
- Optional proposed-quantity check at upload time
- Every extraction logged with the model that ran it
Every decision, attributable and timestamped.
Decision history shows every intake evaluation Chemsana has run for your site — most recent first — with the rules that fired, the math behind them, and a filterable log for audits.
- Allowed / Flag / Block counts at a glance
- Filter by verdict and date range
- Drill into any row for the full reasoning
An operating system for chemical compliance.
Eight purpose-built engines work together so a single intake decision reflects the full regulatory picture.
SDS ingestion & extraction
AI-powered extraction of CAS numbers and composition, including blended mixtures and synonym handling.
Inventory engine
Multi-source intake from API, CSV, or manual entry. Tracks site-wide totals at the CAS level, not the product level.
Regulatory engine
3,748 regulations loaded across EPA, OSHA, and RCRA — thresholds, chemical lists, and mixture rules included.
Decision engine
Real-time Allowed / Flag / Block output based on inventory, usage, and active permits — not a static report.
Validation & conversion
Reliable gallons-to-pounds conversions with user-defined density references and override inputs when SDS data is incomplete.
Future-state modeling
Simulate new chemicals, process changes, and replacements up to two years ahead — before you commit to a permit application.
The teams who own chemical risk.
EHS & compliance managers
Stop chasing SDS sheets and aggregating spreadsheets. Make decisions with regulatory citations attached.
Plant & operations leaders
Approve new chemicals at the speed of operations — without surprising the permit office six months later.
Environmental consultants
Replace manual threshold workflows with a defensible system of record clients can audit in minutes.
