Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 5-Nitroimidazole-4-carboxylate.
CATO supplies Methyl 5-Nitroimidazole-4-carboxylate (CAS 20271-20-9), a certified reference material (molecular formula C5H5N3O4, MW 171.11 g/mol) for analytical method development and quality control.
Structurally, Methyl 5-Nitroimidazole-4-carboxylate (C5H5N3O4) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 171.11 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
