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-Bromo-6,7,8,8a-tetrahydro-5aH-cyclopenta[5,6][1,4]dioxino[2,3-b]pyridine.
2-Bromo-6,7,8,8a-tetrahydro-5aH-cyclopenta[5,6][1,4]dioxino[2,3-b]pyridine (CAS 1956334-58-9) is a high-purity analytical reference standard with the molecular formula C10H10BrNO2 and a molecular weight of 256.10 g/mol.
The molecular framework of 2-Bromo-6,7,8,8a-tetrahydro-5aH-cyclopenta[5,6][1,4]dioxino[2,3-b]pyridine (C10H10BrNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Bromo-6,7,8,8a-tetrahydro-5aH-cyclopenta[5,6][1,4]dioxino[2,3-b]pyridine 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.
