Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,5-Dimethyl-2-phenyl-1,3,2-dioxaborolane.
CATO supplies 4,5-Dimethyl-2-phenyl-1,3,2-dioxaborolane (CAS 6638-68-2), a certified reference material (molecular formula C18H28N3O3ZnCl, MW 435.27 g/mol) for analytical method development and quality control.
Structurally, 4,5-Dimethyl-2-phenyl-1,3,2-dioxaborolane (C18H28N3O3ZnCl) contains a salt form, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 435.27 g/mol, it falls into the moderately-high-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.
