Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
silicon nitride (CAS 12033-89-5), molecular formula N4Si3 and molecular weight 140.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an inorganic composition, silicon nitride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
