Chemical Structure

4-Fluoropyridine-3-sulfonyl chloride CAS 1060809-59-7 chemical structure

Description

The occurrence of 4-Fluoropyridine-3-sulfonyl chloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Fluoropyridine-3-sulfonyl chloride (CAS 1060809-59-7) is a high-purity analytical reference standard with the molecular formula C5H3ClFNO2S and a molecular weight of 195.60 g/mol.

4-Fluoropyridine-3-sulfonyl chloride (C5H3ClFNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-Fluoropyridine-3-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.
