Chemical Structure
Description
2-(4-Bromophenyl)-5-propyltetrahydro-2H-pyran (CAS 1670235-54-7), molecular formula C14H19BrO and molecular weight 283.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-(4-Bromophenyl)-5-propyltetrahydro-2H-pyran is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-(4-Bromophenyl)-5-propyltetrahydro-2H-pyran 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.
