Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-Chloro-2-oxoethyl)ferrocene.
(2-Chloro-2-oxoethyl)ferrocene (CAS 42552-70-5) is a high-purity analytical reference standard with the molecular formula C12H11ClFeO and a molecular weight of 262.51 g/mol.
Owing to a salt form, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, (2-Chloro-2-oxoethyl)ferrocene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 262.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Chloro-2-oxoethyl)ferrocene 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.
