Description
As a certified reference material (CRM), 2-hydroxycyclohepta-2,4,6-trien-1-one- formaldehyde(1:1) 2836-82-0 AR-1E2547 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-hydroxycyclohepta-2,4,6-trien-1-one- formaldehyde(1:1) 2836-82-0 AR-1E2547 (CAS 2836-82-0) is a high-purity analytical reference standard with the molecular formula C9H9FO and a molecular weight of 152.17 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2-hydroxycyclohepta-2,4,6-trien-1-one- formaldehyde(1:1) 2836-82-0 AR-1E2547 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.17 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
