Chemical Structure
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.
Methyl 1-(trimethylsilyl)cyclopropane-1-carboxylate (CAS 40195-35-5) is a high-purity analytical reference standard with the molecular formula C8H16O2Si and a molecular weight of 172.30 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Methyl 1-(trimethylsilyl)cyclopropane-1-carboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
