Chemical Structure
Description
4-(2,4-Difluorophenoxy)butane-1-sulfonyl chloride (CAS 1375068-02-2) is a high-purity analytical reference standard with the molecular formula C10H11ClF2O3S and a molecular weight of 284.71 g/mol.
Structurally, 4-(2,4-Difluorophenoxy)butane-1-sulfonyl chloride (C10H11ClF2O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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 284.71 g/mol, it falls into the medium-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), 4-(2,4-Difluorophenoxy)butane-1-sulfonyl chloride 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.
