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 5-Ethoxy-1,3-dimethyl-1H-pyrazol-4-amine.
5-Ethoxy-1,3-dimethyl-1H-pyrazol-4-amine (CAS 87675-30-7), molecular formula C7H13N3O and molecular weight 155.20 g/mol, is a CATO reference standard with documented purity and traceability.
5-Ethoxy-1,3-dimethyl-1H-pyrazol-4-amine (C7H13N3O) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
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.
