As a certified reference material (CRM), 2-(((1-(Bromomethyl)cyclopentyl)oxy)methyl)tetrahydro-2h-pyran 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.
2-(((1-(Bromomethyl)cyclopentyl)oxy)methyl)tetrahydro-2h-pyran (CAS 1247648-51-6), molecular formula C12H21BrO2 and molecular weight 277.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 2-(((1-(Bromomethyl)cyclopentyl)oxy)methyl)tetrahydro-2h-pyran is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
