It is also sold as 1-Fluoro-2,4-dinitrobenzene, DNFB, FDNB, Sanger's reagent. All refer to CAS 70-34-8. Confirm the CAS number with any supplier before ordering.
Price depends on grade, volume, packing, Incoterm and destination port, and moves with raw material markets. Send us your requirement and we will quote in EUR or USD with a landed-cost breakdown, usually within one business day.
2,4-Dinitro Fluoro Benzene is a highly electrophilic aromatic used to label amino groups in peptide and protein chemistry and as a reactive building block in synthesis.
Standard grade offers 98.0% minimum GC purity. Premium grade offers 99.0% minimum, lower water content and inert-gas blanketed packaging. Premium is recommended for multi-step routes with tight impurity control.
Frederick Sanger used it to label the N-terminal amino group of insulin, a step in the first protein sequencing work.
DNFB is a strong skin sensitiser and toxic. It needs closed handling, suitable PPE and the controls set out in the current SDS. Ask us for the SDS before ordering.
Store tightly closed in a cool, dry, dark place away from bases, amines and moisture, per SDS. Use within the shelf life stated on the COA and TDS.
It is treated as a dangerous good (class and UN number per SDS; always confirm on the current SDS). We pack it in UN-approved containers, apply CLP labels and ship through licensed forwarders under IMDG for sea and ADR for European road.
Yes. Laboratory and pilot samples are supplied with a COA and SDS so your team can qualify the grade. Mention sample needs in your enquiry.
REACH status is confirmed before we quote. We advise on importer-of-record arrangements and whether the substance is registered for your use. Send your use descriptor and we will confirm.
