4-Bromo-5-(difluoromethyl)-3-iodo-2-methylpyridine CAS 1805409-39-5 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-Bromo-5-(difluoromethyl)-3-iodo-2-methylpyridine.

4-Bromo-5-(difluoromethyl)-3-iodo-2-methylpyridine (CAS 1805409-39-5) is a high-purity analytical reference standard with the molecular formula C7H5BrF2IN and a molecular weight of 347.93 g/mol.

Structurally, 4-Bromo-5-(difluoromethyl)-3-iodo-2-methylpyridine (C7H5BrF2IN) contains a nitrile group, fluorine/bromine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 347.93 g/mol, it falls into the moderately-high-molecular-weight range. 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), 4-Bromo-5-(difluoromethyl)-3-iodo-2-methylpyridine 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.
