Chemical Structure

4-(3-Chloro-6-methoxyphenyl)-4-oxobutyric acid CAS 854879-20-2 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 4-(3-Chloro-6-methoxyphenyl)-4-oxobutyric acid.

4-(3-Chloro-6-methoxyphenyl)-4-oxobutyric acid (CAS 854879-20-2) is a high-purity analytical reference standard with the molecular formula C10H7ClF2O3 and a molecular weight of 248.61 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 4-(3-Chloro-6-methoxyphenyl)-4-oxobutyric acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.61 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), 4-(3-Chloro-6-methoxyphenyl)-4-oxobutyric acid 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.
