Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 831-82-3 D83R742GJR p-Phenoxyphenol Phenol, p-phenoxy- (8CI) Phenol, 4-phenoxy- 4-Phenoxyphenol EINECS 212-611-1 p-Hydroxydiphenyl ether 4-Hydroxydiphenyl ether NSC 25027 UNII-D83R742GJR.

CATO supplies 831-82-3 D83R742GJR p-Phenoxyphenol Phenol, p-phenoxy- (8CI) Phenol, 4-phenoxy- 4-Phenoxyphenol EINECS 212-611-1 p-Hydroxydiphenyl ether 4-Hydroxydiphenyl ether NSC 25027 UNII-D83R742GJR (CAS 831-82-3), a certified reference material (molecular formula C12H22O2, MW 198.30 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H22O2, 831-82-3 D83R742GJR p-Phenoxyphenol Phenol, p-phenoxy- (8CI) Phenol, 4-phenoxy- 4-Phenoxyphenol EINECS 212-611-1 p-Hydroxydiphenyl ether 4-Hydroxydiphenyl ether NSC 25027 UNII-D83R742GJR contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 198.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
