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 (5-Ethoxy-3-methyl-3H-imidazo[4,5-b]pyridin-2-yl)methanol.
(5-Ethoxy-3-methyl-3H-imidazo[4,5-b]pyridin-2-yl)methanol (CAS 172648-40-7) is a high-purity analytical reference standard with the molecular formula C10H13N3O2 and a molecular weight of 207.23 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (5-Ethoxy-3-methyl-3H-imidazo[4,5-b]pyridin-2-yl)methanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.23 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
