Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including WQ89QF16O3 3468-99-3 Ethyl diphenylacetate UNII-WQ89QF16O3 Acetic acid, diphenyl-, ethyl ester Diphenylacetic acid ethyl ester Diphenylacetic acid ethyl ester [MI] Ethyl 2,2-diphenylacetate NSC-17496.

CATO supplies WQ89QF16O3 3468-99-3 Ethyl diphenylacetate UNII-WQ89QF16O3 Acetic acid, diphenyl-, ethyl ester Diphenylacetic acid ethyl ester Diphenylacetic acid ethyl ester [MI] Ethyl 2,2-diphenylacetate NSC-17496 (CAS 3468-99-3), a certified reference material (molecular formula C16H16O2, MW 240.30 g/mol) for analytical method development and quality control.

Structurally, WQ89QF16O3 3468-99-3 Ethyl diphenylacetate UNII-WQ89QF16O3 Acetic acid, diphenyl-, ethyl ester Diphenylacetic acid ethyl ester Diphenylacetic acid ethyl ester [MI] Ethyl 2,2-diphenylacetate NSC-17496 (C16H16O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 240.30 g/mol, it falls into the medium-molecular-weight range. 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.

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.
