Chemical Structure
Description
As a certified reference material (CRM), 3-Amino-5-phenylthiophene-2-carbohydrazide 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.
CATO supplies 3-Amino-5-phenylthiophene-2-carbohydrazide (CAS 521093-34-5), a certified reference material (molecular formula C11H11N3OS, MW 233.29 g/mol) for analytical method development and quality control.
3-Amino-5-phenylthiophene-2-carbohydrazide (C11H11N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.
