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-Amino-3-methyl-thiophene-2,4-dicarboxylic acid -4-ethyl ester 2-methyl ester.
CATO supplies 5-Amino-3-methyl-thiophene-2,4-dicarboxylic acid -4-ethyl ester 2-methyl ester (CAS 30823-51-9), a certified reference material (molecular formula C10H11N3, MW 173.21 g/mol) for analytical method development and quality control.
5-Amino-3-methyl-thiophene-2,4-dicarboxylic acid -4-ethyl ester 2-methyl ester (C10H11N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-Amino-3-methyl-thiophene-2,4-dicarboxylic acid -4-ethyl ester 2-methyl ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
