Chemical Structure

2,4-Dichloro-5-(methylsulfonyl)pyrimidine CAS 514842-56-9 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 2,4-Dichloro-5-(methylsulfonyl)pyrimidine.

2,4-Dichloro-5-(methylsulfonyl)pyrimidine (CAS 514842-56-9) is a high-purity analytical reference standard with the molecular formula C5H4Cl2N2O2S and a molecular weight of 227.07 g/mol.

The molecular framework of 2,4-Dichloro-5-(methylsulfonyl)pyrimidine (C5H4Cl2N2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 2,4-Dichloro-5-(methylsulfonyl)pyrimidine 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.
