Chemical Structure
Description
2-Amino-3-fluoropyridine-4-thiol (CAS 2460752-77-4), molecular formula C5H5FN2S and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Amino-3-fluoropyridine-4-thiol (C5H5FN2S) contains a nitrile group, sulfur-containing functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 144.17 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Amino-3-fluoropyridine-4-thiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
