(Ethyl methyl-1,2-<SUP>13</SUP>C<SUB>2</SUB>)triphenylphosphine bromide CAS 109376-35-4

Description

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.

(Ethyl methyl-1,2-<SUP>13</SUP>C<SUB>2</SUB>)triphenylphosphine bromide (CAS 109376-35-4) is a high-purity analytical reference standard with the molecular formula C20[13C]2H40O2P Br and a molecular weight of 435.43 g/mol.

Structurally, (Ethyl methyl-1,2-<SUP>13</SUP>C<SUB>2</SUB>)triphenylphosphine bromide (C20[13C]2H40O2P Br) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 435.43 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
