2-chloro-3,5,6-trimethylpyrazine CAS 68303-35-5 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.

2-chloro-3,5,6-trimethylpyrazine (CAS 68303-35-5), molecular formula C7H15ClN2 and molecular weight 162.66 g/mol, is a CATO reference standard with documented purity and traceability.

2-chloro-3,5,6-trimethylpyrazine (C7H15ClN2) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
