2,5-Dichloro-4-methylphenacyl chloride CAS 1806347-89-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Dichloro-4-methylphenacyl chloride.

2,5-Dichloro-4-methylphenacyl chloride (CAS 1806347-89-6) is a high-purity analytical reference standard with the molecular formula C9H7Cl3O and a molecular weight of 237.51 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,5-Dichloro-4-methylphenacyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.51 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2,5-Dichloro-4-methylphenacyl 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.
