2-(5-ethylpyridin-2-yl)ethan-1,1,2,2-d4-1-ol CAS 1189881-19-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5-ethylpyridin-2-yl)ethan-1,1,2,2-d4-1-ol.

2-(5-ethylpyridin-2-yl)ethan-1,1,2,2-d4-1-ol (CAS 1189881-19-3), molecular formula C9H9D4NO and molecular weight 155.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(5-ethylpyridin-2-yl)ethan-1,1,2,2-d4-1-ol (C9H9D4NO) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 2-(5-ethylpyridin-2-yl)ethan-1,1,2,2-d4-1-ol 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.
