Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 613-91-2 Acetophenone oxime Ethanone, 1-phenyl-, oxime 3-07-00-00954 (Beilstein Handbook Reference) AI3-10567 BRN 1562059 EINECS 210-360-2 Methyl phenyl ketone oxime Methyl phenyl ketoxime NSC 3988 NSC 52223.

613-91-2 Acetophenone oxime Ethanone, 1-phenyl-, oxime 3-07-00-00954 (Beilstein Handbook Reference) AI3-10567 BRN 1562059 EINECS 210-360-2 Methyl phenyl ketone oxime Methyl phenyl ketoxime NSC 3988 NSC 52223 (CAS 613-91-2) is a high-purity analytical reference standard with the molecular formula C8H15NO and a molecular weight of 141.21 g/mol.

Structurally, 613-91-2 Acetophenone oxime Ethanone, 1-phenyl-, oxime 3-07-00-00954 (Beilstein Handbook Reference) AI3-10567 BRN 1562059 EINECS 210-360-2 Methyl phenyl ketone oxime Methyl phenyl ketoxime NSC 3988 NSC 52223 (C8H15NO) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 141.21 g/mol, it falls into the low-molecular-weight range. 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.

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.
