Chemical Structure
Description
As a certified reference material (CRM), 2-aminobutane-1-thiol 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.
2-aminobutane-1-thiol hydrochloride (CAS 4145-99-7) is a high-purity analytical reference standard with the molecular formula C4H11NSHCl and a molecular weight of 141.66 g/mol.
2-aminobutane-1-thiol hydrochloride (C4H11NSHCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
