Chemical Structure

Spiro[3.5]Nonan-5-one CAS 7141-75-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Spiro[3.5]Nonan-5-one (CAS 7141-75-5) is a high-purity analytical reference standard with the molecular formula C9H14O and a molecular weight of 138.21 g/mol.

Owing to a hydroxyl group, an ether linkage, Spiro[3.5]Nonan-5-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.21 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).

As a certified reference material (CRM), Spiro[3.5]Nonan-5-one 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.
