Description

Compared with other compounds in its class, the molecular weight of 148.59 g/mol gives 5-Methylfuran-2-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Methylfuran-2-carbonyl chloride (CAS 14003-11-3), molecular formula C6H9ClO2 and molecular weight 148.59 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-Methylfuran-2-carbonyl chloride (C6H9ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 148.59 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 5-Methylfuran-2-carbonyl chloride 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.
