Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-Hydrazinyl-5,6,7,8-tetrahydro-2-methyl[1]benzothieno[2,3-d]pyrimidine (CAS 77995-54-1), a certified reference material (molecular formula C11H14N4S, MW 234.32 g/mol) for analytical method development and quality control.
4-Hydrazinyl-5,6,7,8-tetrahydro-2-methyl[1]benzothieno[2,3-d]pyrimidine (C11H14N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.
CATO manufactures 4-Hydrazinyl-5,6,7,8-tetrahydro-2-methyl[1]benzothieno[2,3-d]pyrimidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
