5-(((2-Cyanoethyl)thio)methyl)furan-2-carboxylic acid CAS 90564-11-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(((2-Cyanoethyl)thio)methyl)furan-2-carboxylic acid.

5-(((2-Cyanoethyl)thio)methyl)furan-2-carboxylic acid (CAS 90564-11-7), molecular formula C9H9NO3S and molecular weight 211.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-(((2-Cyanoethyl)thio)methyl)furan-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 5-(((2-Cyanoethyl)thio)methyl)furan-2-carboxylic acid 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.
