Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4792-78-3 2-(2-Hydroxyethoxy)phenol Phenol, 2-(2-hydroxyethoxy)- Catechol, mono(beta-hydroxyethyl)ether EINECS 225-346-1 o-(Hydroxyethoxy)phenol 2-(beta-Hydroxyethoxy)phenol.
4792-78-3 2-(2-Hydroxyethoxy)phenol Phenol, 2-(2-hydroxyethoxy)- Catechol, mono(beta-hydroxyethyl)ether EINECS 225-346-1 o-(Hydroxyethoxy)phenol 2-(beta-Hydroxyethoxy)phenol (CAS 4792-78-3), molecular formula C8H16O3 and molecular weight 160.21 g/mol, is a CATO reference standard with documented purity and traceability.
4792-78-3 2-(2-Hydroxyethoxy)phenol Phenol, 2-(2-hydroxyethoxy)- Catechol, mono(beta-hydroxyethyl)ether EINECS 225-346-1 o-(Hydroxyethoxy)phenol 2-(beta-Hydroxyethoxy)phenol (C8H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
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.
