Chemical Structure
Description
2-(2-Oxocyclohexyl)acetyl chloride (CAS 342402-77-1), molecular formula C8H11ClO2 and molecular weight 174.62 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(2-Oxocyclohexyl)acetyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.62 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.
As a certified reference material (CRM), 2-(2-Oxocyclohexyl)acetyl chloride 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.
