3-Nitro-7,8-dihydro-5H-pyrano[4,3-b]pyridin-2-amine CAS 1260666-63-4 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 3-Nitro-7,8-dihydro-5H-pyrano[4,3-b]pyridin-2-amine.

3-Nitro-7,8-dihydro-5H-pyrano[4,3-b]pyridin-2-amine (CAS 1260666-63-4) is a high-purity analytical reference standard with the molecular formula C8H9N3O3 and a molecular weight of 195.18 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-Nitro-7,8-dihydro-5H-pyrano[4,3-b]pyridin-2-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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 3-Nitro-7,8-dihydro-5H-pyrano[4,3-b]pyridin-2-amine 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.
