Compound Overview
N-Formyl-L-histidine, also known as Formyl-L-histidine, binds histidyl-tRNA synthetase with a Ki of 4.6 μM. It also competitively inhibits L-histidine ammonia-lyase, blocking the formation of urocanic acid from L-histidine with a Ki of 4.26 mM[1][2]. It is supplied as a white to off-white solid (C7H9N3O3, MW 183.16) at 99.89% purity.

In Vitro
| Solvent | Solubility | Notes |
|---|---|---|
| DMSO | 10 mg/mL (54.60 mM) | requires sonication and warming and heat to 60°C; use freshly opened DMSO (absorbed moisture lowers solubility) |
Aliquot the stock solution and store it at -80°C (up to 6 months) or -20°C (up to 1 month); sealed storage, away from moisture; avoid repeated freeze-thaw cycles.

Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.
- Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
- Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
- Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
- QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
- Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity
To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
