Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Amino-5-ethylphenol hydrochloride (CAS 149861-22-3) is a high-purity analytical reference standard with the molecular formula C8H11NOHCl and a molecular weight of 173.64 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Amino-5-ethylphenol hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-Amino-5-ethylphenol 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.
