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 methyl rel-(1R,2R,4R)-2-fluoro-7-oxabicyclo[2.2.1]hept-5-ene-2-carboxylate.
methyl rel-(1R,2R,4R)-2-fluoro-7-oxabicyclo[2.2.1]hept-5-ene-2-carboxylate (CAS 1624052-25-0), molecular formula C8H9FO3 and molecular weight 172.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, methyl rel-(1R,2R,4R)-2-fluoro-7-oxabicyclo[2.2.1]hept-5-ene-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.15 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 methyl rel-(1R,2R,4R)-2-fluoro-7-oxabicyclo[2.2.1]hept-5-ene-2-carboxylate 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.
