Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 217.65 g/mol gives ethyl 2-hydroxy-2-(pyridin-3-yl)acetate hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies ethyl 2-hydroxy-2-(pyridin-3-yl)acetate hydrochloride (CAS 1269151-93-0), a certified reference material (molecular formula C9H11NO3HCl, MW 217.65 g/mol) for analytical method development and quality control.
ethyl 2-hydroxy-2-(pyridin-3-yl)acetate hydrochloride (C9H11NO3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 ethyl 2-hydroxy-2-(pyridin-3-yl)acetate hydrochloride 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.
