Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-2-(2-((((2-chloro-6-fluorobenzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)-4-methoxynicotinonitrile.
(E)-2-(2-((((2-chloro-6-fluorobenzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)-4-methoxynicotinonitrile (CAS 339103-13-8) is a high-purity analytical reference standard with the molecular formula C19H14ClFN4O2 and a molecular weight of 384.79 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (E)-2-(2-((((2-chloro-6-fluorobenzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)-4-methoxynicotinonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), (E)-2-(2-((((2-chloro-6-fluorobenzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)-4-methoxynicotinonitrile 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.
