Autopilot

The index writes itself, around the clock.

A background worker pulls from PubChem, ECHA and OSHA every two minutes. Substances you search for but that are missing get promoted automatically to the top of the queue. No human in the loop.

The index

Built for lab benches, not marketing decks.

01

Sourced facts

Every property, hazard statement and pictogram cites its public source: PubChem, ECHA, OSHA or GESTIS.

02

One page, no tabs

Structure, hazards, storage, PPE, transport, first aid. Everything a bench chemist actually reads, on a single scrollable page.

03

Search that thinks in CAS

Type 67-64-1, a formula, or a synonym. We resolve it and open the right sheet.

04

Compare side by side

Pit acetone against ethanol on flash point, LD50, GHS class and compatibility.open

Free tools

Calculators, generators, decoders.
