Chemical Structure
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 1-Ethyl-3-guanidinothiourea hydrochloride (CAS 381670-29-7), a certified reference material (molecular formula C4H11N5SHCl, MW 197.69 g/mol) for analytical method development and quality control.
1-Ethyl-3-guanidinothiourea hydrochloride (C4H11N5SHCl) contains sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
As a certified reference material (CRM), 1-Ethyl-3-guanidinothiourea hydrochloride 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.
