Chemical Structure

2-Furancarboxylic acid, 4-chloro-5-cyano- CAS 1781908-24-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Furancarboxylic acid, 4-chloro-5-cyano-.

2-Furancarboxylic acid, 4-chloro-5-cyano- (CAS 1781908-24-4) is a high-purity analytical reference standard with the molecular formula C6H2ClNO3 and a molecular weight of 171.54 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-Furancarboxylic acid, 4-chloro-5-cyano- is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

CATO manufactures 2-Furancarboxylic acid, 4-chloro-5-cyano- under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
