4-(4-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile CAS 1708251-15-3 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-(4-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile.

CATO supplies 4-(4-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile (CAS 1708251-15-3), a certified reference material (molecular formula C15H10BrClN2O, MW 349.61 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 4-(4-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.61 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).

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.

CATO manufactures 4-(4-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
