Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Ethenyl-2,3-dihydrobenzo[b]furan.
CATO supplies 5-Ethenyl-2,3-dihydrobenzo[b]furan (CAS 633335-97-4), a certified reference material (molecular formula C10H10O, MW 146.19 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 5-Ethenyl-2,3-dihydrobenzo[b]furan is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.19 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.
CATO manufactures 5-Ethenyl-2,3-dihydrobenzo[b]furan 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.
