About Solvent Selector

Solvent Selector is a free, browser-based reference for laboratory solvents — a searchable, interactive version of the miscibility charts and property tables that otherwise only exist as scattered PDFs. It covers HPLC/GC solvent miscibility, UV cutoff, Snyder polarity index and selectivity, boiling point, viscosity, refractive index, USP residual-solvent class, and safety flags.

Who makes it

Hemant Rawat is an independent software engineer who builds free, browser-based reference tools. He compiles each dataset here from primary and U.S.-authoritative chemistry references (NIST, PubChem, USP, and the published chromatography literature) and cites every value. He is not a chemist or laboratory-safety professional — this site is a reference, not professional or safety advice.

Why it exists

Chromatographers, QC and CRO analysts, and chemistry students repeatedly look up the same facts: "are these two solvents miscible?", "what's the UV cutoff of acetonitrile?", "which solvent is UV-transparent and water-miscible?". This site answers those in one place, with every value traced to a public source and a visible "last reviewed" date.

What it is not

It is a reference, not professional or safety advice, and it is not reviewed by a practicing analytical chemist. Property values are typical figures that vary between sources and with temperature; miscibility is general guidance, not a bench test. Always confirm critical values against primary references and the Safety Data Sheet. See our methodology for exactly how the data is compiled and verified.
