Chemistry you can trust, sourced with rigour.
ChemRexn Private Limited is a chemical synthesis, import and distribution company supplying research-grade materials to laboratories, universities and industry across Pakistan.
Bridging global supply and the local bench.
We started ChemRexn to solve a problem familiar to every lab in the region: getting consistent, well-documented reagents without long lead times or opaque sourcing.
Today we import directly from vetted manufacturers in China, verify every batch against its certificate of analysis, and distribute nationwide — pairing global pricing with local support and a chemist you can actually talk to.
- Direct manufacturer relationships, no middle layers
- COA & SDS documentation on every shipment
- Cold-chain and hazmat-compliant logistics
Principles, not just products.

Held to recognised standards.
