Chemical Structure
Description
CATO supplies Tetramethyl orthocarbonate (CAS 1850-14-2), a certified reference material (molecular formula C5H12O4, MW 136.15 g/mol) for analytical method development and quality control.
The molecular framework of Tetramethyl orthocarbonate (C5H12O4) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
